Hi Falko,
I've ran into a weird problem with some graphics files which, as far as I know, work fine in OpenXCom. When I try to "fix palette" in the palette converter, I get a whole bunch of bright green pixels over colors that should remain as they are. I've attached one of the images. I've been using it for a while in game without issue.
Any idea what's happening? Did I mess up the palette of it but somehow OpenXCom displays them properly?
Thanks!
