Care to elaborate? What "bugs" are you referring too? I mean, this is nothing on the scale of the BF4 release by the way!!
That would be kind of hard - I notice easily a dozen (not an exaggeration) different bugs rated between moderate and game breaking in the first ~1 minute of playing the retail BF4 (multiplayer) on release - including:
Invisible players (that took about 2 minutes to load in models - but could see the gun)
Half the sounds not working properly or missing entirely
Problems navigating simple terrain
Trade kills/rate of fire/update rate related issues
Invisible surfaces absorbing bullets
Weapons randomly not firing or cycling very fast without actually doing any damage
"Levolution" crashing the server
Numerous problems with physics around destructible structures
Completely random KIAs
"netcode" in general being ****
Kills not being registered properly
Why on earth I didn't get it refunded there and then I don't know - probably because I played the beta which generally was in a better shape somehow than the release game.
Would be hard to top that for any game.
