Gibs don't appear when I break crate or something

Whenever I break a crate, or any breakable object it instantly disappears instead of breaking apart.

Never mind, I discovered it’s because I have too many physics objects.

My map only has about 830 physics props now.
Breakable props still instantly disappear when I attack them.

Oops, thought it would auto merge.

Eight-hundred and thirty. :colbert:

…What the hell are you making?

A school.

With physics chairs and tables.
