The disappearing item glitch is pretty well documented. Can start happening around 1400 pieces and more frequently with high physics and FX budgets too. Having too many scripts can get it there too.



Can also make players disappear as well. That's because technically players are also items and they also add a decent chunk to the FX budget per player.



It makes things at random disappear but most frequently it's items you placed after you passed the threshold for issues. It also mainly effects physical items but I've seen it do it to invis walls inside forge as well.



It's also not a guaranteed issue either. I've seen several maps with 1600 counts on them that arent affected by the issue so it's a tricky bit. Hopefully you are able to reduce your budgets to work past it.
