I selected the Cockney VA for my character. After about 3 matches it changed to the irish VA, David Whatshisface. So I remade my character and continued. Same thing. I tried again and, yet again, the voice changed back to David’s. Other people have reported this problem, and it seems to be a bug in character attributes rather than in sound files - the VA is stuck as the Security version (calls enemies bandits, regardless of side) and my teammates often call enemies Bandits as well, in the irish accent.
Also, it seems in certain servers I even default to a basic archetype, as do other players.
Is there any way to fix this without losing my level 12 character?
