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.
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.
