entering UNKNOWN ZONE (temple of sol a), Disconnect every time I use worker sledgemal

[Extunarian]

Sounds like a pretty crazy problem...especially with the jumping.

Sol Ro says 'unknown zone' for me as well, and I've never had problems zoning in.

I had odd zoning problems too right when kunark came out. I found I had to reinstall the game. I would try that, especially if you upgraded to the higher quality textures
