Stuff go invinsible?

[TTTT]

Yo again guys. well this map ive been working with have gotten upfucked bad. Any "objective" such as SD bombs, headquarters and any brush_scriptmodel are invinsible. also, grenades, GL bullets, and C4 cant be seen and no explosian will happen althou you still die if youre close. Note that all objectives still works but just cant be seen. i can clearly see them in radiant but not ingame. i have never seen this "error" before and google didnt help

[TTTT]

Nevermind guys, delete this topic. it was an enigne failiure, i had too many entities in my map. sorry for interrupting

Probably best to keep the topic in the off-chance that someone else who gets this problem finds it through searching
