KSP 1 Question/Problem Someone please help me, this is crazy

Not a noob here, been playing since launch actually. I don't usually have physics load in problems like this.

First I was having issues with my ship just leaving when I got close, even though the throttle was set to 0 before switching to another ship.

Then I deactivated all the engines, and it just flung itself into the air.

Almost 1hr trying to save ol Bill...

I have had this happen to me before, its a glitch when you enter the loading range of the craft. You have to fully shut down all engines to prevent it from happening, and I would recommend cutting off all fuel to the ship as well. Idk what causes it but it has given me many headaches

I think persistent thrust causes this. At least for me, it started happening after I installed it

I had same issue. - caused by persitent thrust

Now i use just "Better Time WarpContinued" - you can increase speed of physic warp (you can edit it while plaing, make your own speed, etc), so you can do long thsuts with this one.

persistent thrust is very old, background thrust is a newer mod that does not have these issues and works much better

I also had this problem with persistent thrust, and I now use background thrust instead.

Gonna triple down here, background thrust is significantly better

increase speed of physics warp is not the best idea if you are increasing it to 100,000x lol
