Two of my party members seem to have had their hair and skin turn purple at some point. Anyone else encounter this glitch yet or found a workaround for it yet?

Yes, I've just got Khalida and she turned purple within seconds of finding her. Hopefully a fix will be forthcoming as I keep thinking she's got some awful disease or something! :)

Well I've actually found out how to fix this problem. All you need to do is go into the scripts (Avadon 2/Avadon 2 Files/Scripts) and edit the file av2itemschars.txt. Ctrl-F for the names of the companions and remove all the lines that have cr_graphic_coloradj in them and then you have normal coloured companions again :)

Thanks to the spiderweb forums for providing the fix :)

Well yes, apparently they were! It done so that the player wouldn't get confused between your own character and any joinable NPCs, especially if they are the same class as you. I'm just so glad that I don't have to see bright pink and purple sprites any more :)
