Hm, then I'll take a look into fixing that for the next update.
I recommend you use the non-beta version for now if you're using my program a lot, until I find out what's causing the issue.
Hey! One more question - does this program automatically change the coordinates to Unity's? In Blender we change up to y and forward to positive Z. If not, can you add that as an option too? That would then allow us to skip Blender.
The program converts to Unity's coordinate systems, so up on your model remains up in Unity and other game engines.
