Thanks! I will. Right now I'm noticing that formations got much worse in r28. They were already very buggy before, so these new bugs will really be frustrating. I'll try help on this first as it might still be time for bug fixs for r28.

It isn't witchcraft. You've done much already (creating the fork, clone, branch, and finally the PR) and I'm confident you'll figure out the rest too as we move along. Then I suggest that you create the PR.

When exporting, select the prop point empty first and then the parent object while holding Ctrl

I used the the "biped_meshes_and_animations" armature and weight painted. The model was working fine in-game with the female citizen animations but when the model tried to mine or gather, this error came up. I took a look inside blender and their was a "prop-weapon_R" as a child of the "hand" bone. I then checked the DAE in my code editor and found 6 uses of "weapon_R". Then I checked a vanilla female worker and the uses were the same... You guys know any reason that this error is coming up, and how to fix it?

I assume you mean that the civ is set to random by default?
