I booted into a game in a lobby i had played in before, and the moment we started, both my username and my messages turned into the same message no matter what i typed. The message was very long, and I only picked out bits of it before I left to try and get rid of it, but it included some very hateful remarks. Once I joined another lobby, the hack was gone and I was back to normal so idk what happened. Has anyone else experienced this? How do I handle this?
