Freezing on map startup

[tklamka]

So,

I was working on a custom map in the editor, which previously worked flawlessly, and then decided to add around 50 (+-) grass objects. All were set not to collide with enviroment. But upon startup, a had like 0.5 FPS, couldnt move and i still heard only the main menu music, although on the screen there as already the custom map. Had to crtl alt del out of it after like 3 minutes of waiting.

I thought that colliding objects might be the problem, so i decided to delete all the grass that i added previously. But no luck, what previously worked, now does not, since i have the same problem again. And no, there are no carpets / matresses in the map that might collide with other objects / entities.

I tried starting it up multiple times but still no luck.

Any guess what might be the source of the trouble ?
