Gotta be honest I'm calling it a server issue too since this is the first time I'm hearing about this after 5 months of being rigorously played on SG.
This fucker is so packed full of shit that I had to use point_templates and a command at the end of a round to kill the triggers, buttons and hats so that it would keep from crashing. It's perfectly timed so that it's barely noticeable before the next round starts, just under fifteen seconds after the round ends to be exact. But on this server the next round starts 10 seconds after a round ends so that's probably throwing all that off.
I had a feeling this would be a problem on this server so I'm not surprised, and if you're convinced the problem is on my end we'll I'm gonna call bullshit on that one.
