happend on zm_cave_new

i got infected and some meter for me some guys were infected by a zombie or 2 normally then it kicked me out of game and this was in the console.

but this errormessage is a little bit different then the one of agito in the cs2.

its the same error. even if something else is written there.
its the usual problem with the cache of hlds.

i've noticed that the svc bad mostly comes when round ends, new one started and mostly you will get kicked when have the say open because with that i was fly some times in some seconds ago.
