[Bug report] Crash due to custom weapons files

Hey,

any mod which uses custom weapons file, will crash sooner or later.

The weapons files are causing this error

ERROR: Exceeded MAX_SURFACE_TYPE_SOUND_LISTS (16)

after a certain amount of map changes.

The lower the roundlimit was, the sooner the error appeared.

If i set the roundlimit very low (2 rounds), the server crashes after about 2 hours.

I have tested it with ~40 weapon files and with just one (frag_grenade_mp) and i got the same result.

When i remove the weapon files the mod runs stable.

Its seems like the error always happens on/after map change:
