Weird things in sfs

I'll put all the weird things or bugs I find here.

I was playing around with some stretched docking ports and I tried to make an icarii drive( I think it's called that). My setup involved some stretched ports on the bottom and small ports on the top which were obstructed from the larger pets, the small ports would detached from the larger port craft which gave it 1m/s. I think I did something wrong so I just gave up and made this:

When it's launched the small docking ports all clump together and stick to the top of the.stretched ports. If no gravity is on and you spin in a direction the capsule craft and small docking ports with start to go farther away from each other and you eventually slingshot, I got around 11 m/s doing it.
Going to show it in action.

Video of it in action, I know the quality sucks, I'm trying to find a way to get a good quality gif here.

Funny :p

I knew that those docking ports had an excessive attraction force!

So a few days ago I was watching one of Scott Manley's old videos about breaking the laws of physics with fuel pumps, I'll link the video at the end of this post ( tell me if I break a rule), and I did something similar in sfs. If you have a setup like this:
Screenshot_20220319-122505.png

you can see that the camera is aiming at the center of mass (I think) which is higher than the probe, this is because the top fuel tank has full fuel and the bottom one has no fuel.

In this screenshot you'll see that now I've flipped the craft and the fully fueled tank is at the bottom, now let's transfer the fuel to the empty tank.

Now my camera or center of mass has moved up as well as the craft, if you look at the height it shows 54.0m instead of 38.1. It moved up 15.9 meters only by transferring fuel.

This can also be used to give the craft momentum without engines, separators, docking ports, or bumping into the ground, though it gives such a little amount so slowly it isn't that useful.

Scott Manley's video
In his video he has a better explanation in KSP.

Nice trick, though it will be hard to exploit this efficiently. You can post a video if you wish. As long as it's related to the topic it's not against the rules.

No, you did not gain momentum. You changed your position. Momentum is speed x mass. And here you don't have speed at any moment.
Now, iirc what used to happen is while transferring fuel in these conditions, the rest of the craft would move the opposite direction, so that the centre of mass wouldn't move. So I assume that was perceived as a bug, and now the craft kinda doesn't move although the CoM does.
Not sure tho, I might not remember correctly

Should have explained more if you transfer fuel to the other side while spinning it can give m/s.

I tried to see if I could make angled docking ports connect correctly and this is what happened.
This is the setup with the two bottom crafts at 45 degrees:
Screenshot_8.png

I have it so the middle craft will dock to the top craft and then the bottom one, this is what happens when the two top crafts dock.
Screenshot_9.png

I switched to the bottom craft and this happened to the other one..
Screenshot_10.png

The parts are all weird but I can still use them as normal. After I disconnect this port it goes back to normal and takes a port with it.

Screenshot_4.png

I connected this to the other craft and got this which will connect to to an identical craft.

Can this be made into a segmented ring?
This is what I ended up with, If tested more I think it could work.

So I was messing around with a shuttle and it's cargo bay, which looks like this:
Screenshot_20220530-045616.png

I have staging so that the fairing gets activated but has detach edges off and some seperator get activated, then I put on RCS, control one half of the bay with an RCS probe thingy and dock the upper port to the side facing one. Then the cargo can be deployed and accessed, that is what is supposed to happen. This is what happened when I try it:
I have the shuttle on the pad with no gravity,

I activate the staging, RCS and undock the port.

Now normally if you didn't move the bay away from the bottom port it would attract it and redock but that doesn't happen.
Screenshot_20220530-050032.png

The bay is docked to the shuttle and locked in place forever, it's similar to the bug I showed before with docking ports. For some reason it locks into place and sometimes bugs out like this:
Screenshot_20220530-045247.png

This is what happened when I opened the bay up. I have not bp edited the shuttle or clipped anything. This may be caused by the recent update, but I don't know.

Just tried to make two small rcs drones undock and redock and this still happens.

This happens to me on every world even new ones can someone test it and tell me if it's just me please.

Oh wow that is a weird bug. You are on the beta, which is probably why this happens.

Honestly that has nothing to do with the beta. That has been happening since 1.4. that happens when you have a large fairing of which one side is attached to your craft and the other to a docking port which is also docked to your craft. Absolutely all of my shuttles for the past two years have suffered from this problem if I did not pop them first before anything else. If you use any docking port before you pop your fairings then this will happen. So the fix is simple. Pop your fairings before anything else and you will have no problems at all.

I gotta test this. Never happened to me, maybe cos I always popped the fairings first. They also cause a massive lag spike

I've never had that bug ever before

I tested this with crafts with no fairings and it still happened.
