My Cloth Sim with Pressure is Acting very Unusually So I've been making this scene with some balloons. They have been absolutely fine until now. The sim plays through absolutely fine (sort of) and then the 2nd time around, even if I bake the sim, it starts going all crazy and i have no idea why. I think it's a bug. I've made the scene exactly the same before, it had self collision and collision with other objects and they were all interacting fine. Then all of a sudden the animation wasn't playing back and kept crashing blender. So I remade this scene and now this is happening.
Here's a link to the blend file 
And Here's a link to a video of the problem: https://vimeo.com/549503971/9e965b00bd
Here's a link to another video with exactly the same setup and it's working fine: https://vimeo.com/549505660
Hope someone can help because it's driving me nuts. Remade this project a few times and goes fine for a while then starts going nuts for some reason.
Many thanks!
i got a &quot;good result&quot; by changing this:

change back gravity on &quot;F&quot; to 1 and applied scale for your cloth object



change gravity speed z on world settings to 10



changed pressure to .1



then i tapped delete all bakes, and bake

got this:
