Killed spider tank in Fanatic Strike, selected it from the directory. One person (me) died from spider tank debree explosion. Two people ran ahead, we wiped since I was the only one in the darkness zone (I think the wall that blocks progress disappears earlier than the marker/ strike step which starts the darkness zone in the next step. Normally you can back track to trigger the update but in this case it was a wipe since I was still dead in the darkness zone and they left it). After we all revived it started us back at the beginning of the first darkness zone. However when we got back to the spider tank, the doorway for the spider take was not there visibly, but prevented us from walking through it. Pressure plate would not go down either. Had to restart strike.
