there is a bug (or something you might want to fix)
When you build a sentry (while you stand still and actually building it) destory the base of the sentry gun (while building it) then the top of the sentry will drop on the ground and spin round and round faster and faster and starts shooting, after bout 8 seconds it spins very fast and shoots very quickly then blows up. (you might want to fix this by not letting the client shoot until the building process is complete)
