at approx. 3:35 AM saturday the 15th, it appears all 4 servers froze. after reconnecting eventually, it it returned to the same map we had been on. not entirely sure what happened.
edit: just happened again 3:38
edit edit: and again, 3:46
maps and other data are saved (i.e. gg didn't come back to jungle (default map) and between second and third crashes, people rejoined w/ same score and level)
nothing out of place in console.
