Got some strange things on the normal server:

CT bots dont shoot at T bots, as if they dont see each other
CT bots dont shoot at T player but seems to react
T bots disappear and show up again
items (the hand-cart with souvenirs and hats) respawns -falls from the sky-
Game stops and continues after 5 seconds

the map was de_tides


(and I wasnt drunk or smoked something )

Just had a go and it looked ok to me, did'nt come across any of the problems mentioned by Hans.

Maybe a weird one off glitch, or the drink ?

Yes all was ok now
