I think it has been mentioned this will be resolved in the next update. Not sure if it was but apparently this happens with other bots too. Official Uber Blitz server just now, round 1, Slim spawned and we couldn't damage it. The bot spawned from the left front and walked across the map out into space. Anything we can do other than leave the server when this happens? Screen shot attached.
