Hi,

I'm making a game which is basically a Vampire Survivors clone - so lots of enemies, projectiles and Actors in general. I've noticed that after a while on mobile especially the game just kinda slows down and crashes. My guess is there's a memory leak somewhere. After checking the code on my side, I can't find any problems, so I decided to take heap snapshots and it seems the Entity Manager _entititiesToRemove array does not get cleared, just gets filled with more entities:

I think this might be the source of the problem. Can you please check and confirm? Thanks
