POSSIBLE SPOILERS :
So I fought the cult leader to save the tari chieftan's daughter and the worshippers were all invisible so I thought hey it's D&D psonic invisible characters and one of them dropped the chameleon gloves so I didn't think anything supsicious there.
But when the tari attacked the skull temple the friendly tari immediatly turned invisible so it was 2 invisible factions fighting each other.
One of my characters was blind so would that cause the entire party to be blind ?
or is it actually a bug?

I am running Windows 7 64 bit.
I installed yesterday and started playing.
I rarely encounter dosbox problems so This one has me baffled it doesn't seem to be going away.

Weird. I've never had that happen. That sounds like a bug. Stuff doesn't turn invisible in these games. Still, there's a campfire in the good Tari warrens. Try resting there and casting "cure blindness" on your blind character. It's worth a try to see if that does anything. I doubt that blindness is your problem, though. The Dark Sun games were kind of buggy, and my playthroughs sometimes have minor issues.

This is a bug in the game itself. I am uncertain what triggers it, but I recall encountering it more often with computer-controlled characters in the party.

It should be a rare occurrence; I've only had it happen a handful of times on numerous playthroughs. I've never had whole factions disappear though, and if it happens on reload there's not much you could probably do about that save. You can bypass the Tari and try moving on FWIW.

thanks for the info guys. Yeah I'll probably just start over I'm getting a feel for this game so it's not like I made it super far.
I noticed some stuff as far as classes I needed to work on anyway.
