Thats because the old texture pack was double-sided. On your old characters, use any dye and it should fix the texture issue.

Thank you. That was very helpful. You've done a great work with this mod. On another topic I found a minor inconvenience in the sense that the Monster Infrequents have the same bright green colors as the rare items instead of the vanilla olive green. This is in the Stash/Inventory browsing which makes it difficult to sort them. Do you think it is a problem at my end or of the mod itself? Thank you in advance

I tried installing the new EGA today (hard mod version) but messed up the character skins, even the newly created ones. I had the march version of EGA and it worked very well. No other mods installed. I have the steam version of the game with all the dlc's. If someone has an answer, thank you in advance.
