i played with my brother 172 and we raced to see who will finish it faster, after that round i transed and i got the normal halloween ( of the halloween body without any trans pack) trans and NOT THE EVENT TRANS. and i didnt tell my pass to anyone, please santa check the logs i swear i bought it from lithuim, ask him.
EDIT : it wasnt gone it was simply hidden on the Trans Pack space, I equiped another trans and the halloween trade went down to the inv lol.
and Santa ignore the last PM about this bug please.
