It’s unfortunate, since it seems like a cool patch, but I’ve never got it to work! I’m wondering if maybe it doesn’t work with the current febuilder, or maybe there’s something I’m missing!
There are more than one of them in FeBuilder, which one are you using?
At least one of them works only for player units, so if you are trying to change enemy/NPC unit portrait, that’d explain it.
The more recent one, by Scraiza
Were you trying to change enemy/npc unit portrait (or player who will turn into either one later)? In my experience it will not then work.
Weird that there’s that limitation, but it did seem to be the problem, thanks!
