Nostalrius Begins - Quality wow vanilla realm (1.12)

With this fluctuation of population on PVP server to often drop and roll back, I went ahead and made a toon in PVE to play on when the servers go down. However, upon making that toon, I was on for as little as 20 seconds before the client crashed. On the very rare occasion, I do experience crashes but usually only once and than I don't see it again for a while. This time, I logged in PVE a total of 4 times, all 4 times resulted in a client crash within 10 seconds of logging. However, I don't experience this issue on PVP.

Not quite sure if it matters but, upon last crash, the map wasn't fully loaded, and I couldn't see or move my toon. I was literally like clipped through the group and could see under Elywnn Forest. xD

Anyway, idk, any solution or is this a known issue?
