The time out bug was patched a long time ago and I don't think what you are experiencing is a server or game issue as such... More custom maps were added last week so I'm guessing the issue may lie here. I will change the map cycle back to some maps we know are working and see if this improves stability.
With all custom maps they are made by people like you and I. They don't have lots of money to throw at their projects so you will experience some glitch here and there. So if you do see the odd weapon or object where it shouldn't be just remember its a custom map with some custom discrepancies which is acceptable when its for free :)
