As you can see from the attached image, my Fire Godlike has Battle Forged still applied even though his endurance is now full. I am running the GOG version and I have the 1.03 patch installed. I thought that was supposed to fix this.

Anyone else having this issue?

Seems like most of these issues are going to take a few patched to finally be done away with. At least they took care of the double click bug 

Yeah but this is specifically an issue that 1.03 was supposed to fix.

Updated to 1.03.0530, issue not resolved.

Supposedly it's supposed to be fixed in 1.05, although I don't think it works retroactively... And Cheat engine cant remove it either. Might try cheat mode in the IE mod, maybe that can remove active effects.

I can second herostratus's comment. In the most current beta build, which claims a fix for effect stacking, my saves are still affected. Appears to not be retroactive.
