I have no much details in the maps and also none complicated enetitys or buttons / trains etc.
There is only the "weapon given on player spawn" which i think might be the reasons for my maps to crash.
If you've got any other idea why it happens please let me know, and remember its randomaly, sometimes it happens after 50 minutes of playing and sometimes after 2 minutes.
*The maps are for CounterStrike 1.6 mod.
Thanks alot,
patriarch.
