Not sure how you can spawn without checking the box stating you're ready to spawn. It's one thing if it were siege or strat, but battle is a bit different. Even though you had your gear bugged, you still chose suicide by running into the opposing team with your fists, rather than attempting to use your high athletics to maneuver around the field until you could loot a weapon, and thus help your team win. I think anyone who has played this mod for a long time has had their gear bug at least once, most people tend to loot a weapon, rather than suicide.
The initial ban length was for 1 day.
