Sent it good sir. So it saves, but it does so inconsistenly. I made a project from scratch vary basic art with only like 4 bones, no character maps or anything and I was happy to see that it saved. so I tried to redo it again just in case, selected a separate folder for saving the generated spritesheets and, It did not save(using that same simple project).
So I thought, maybe it only saves on new fresh projects made from scratch. so I made another project from scratch, added some simple sprites, like arms, a leg and head, like 4 bones only. and it did not save.
