this error just happened to me, anyone knows what this is?

the game crash and i got an error saying

"trying to use null { } when it's not available"

something like that

 

thx

When does it actually occur?

Seems like a server running a bugged mod, in my opinion.

it happened rrandomly, i was in the middle of a round and i got the error

i was playin SnD antinoob i think

Probably the mod, yeah.. anyway just try on other servers not running mods. If it doesn't occur then you're fine.
