Here is your problem.
@grazer is this a memory leak again? Or a physics glitch? And why is it trying to calculate epsilon!?!?
How do I fix it?
@sedricktam flowlab is not perfect, it has many glitches and bugs. Unfortunately, you can do nothing to fix it. I would recommend cloning the game, but ifnthat doesn’t work, just restart. Sorry:(
ok thanks for your help
