NPC's RPG and crossbow not working?

is anyone elses npcs not firing the rpg and the crossbow? i remeber them being able to in the past, but then there was an update. ive been looking for a fix but i havent found one, except for an npc rpg that failed and fired way too many way too fast and as soon as one hit, they trigged the rest which went back to the operator and boom they all died… any fix or dl?

RPG fires after a while, npcs aren’t supposed to use the crossbow.

but mine doesn’t… they just sit there in a pose ready to fire, but nothing more… could i edit something in the .txt files?

Something almost the same happens with the combine, when you use a custom weapon, they move ther hand rarely.
