This is the server that is crashing:

http://www.gametracker.com/server_info/72.5.250.55:27016/

After the last TF2 update (April 20th); anytime that anyone uses the medigun the connection to the server will crash for all clients connected. The server does not crash completely because everyone is able to immediately rejoin, however, it doesn't take long before the server fills up and someone picks Medic, then we all crash again. If you don't believe me, try for yourself (just pulling the gun out doesn't cause the crash, so you'll need someone else on your team to heal).

Also, +throw nades are no longer working. DDR's 32 man purple X server is the only TF2 server I play on these days. Can anyone please help?
