Probably the hack protection being over protective...I think boats go faster than running and about the same speed as flying, and you are not jumping up and down in a boat, so that may trip the sensors, it's happened to me too .
its happened to me as well. mostly when my boat crashes into something and breaks though... but it still happens
This happens all the time when i'm in combat and i lose p4 sets and then i get sad If this could be fixed even a little bit can you do that? Like i understand that you guys don't want people flying but for all the lagging people like me we get kicked often for no reason
