Oh, sorry. I swear I tried googling around for a while first, but I didn't see that thread. Anyways, since this was such a recent bug, I was able to build 19.02.07 and it seems to be working without a hitch. I was able to see a modified pokemon in-game.
Let me know if there's anything I can do to help resolve the bug, but be warned I'm a total noob. The furthest extent of my knowledge is modifying the GBA ASM (poorly). Most of that thread went completely over my head.
