SOLVED: Aseprite 1.3.4 patched in the fix for this :D
Oh your all good, honestly thank you for the heads up on this!
Did some digging in to this and unfortunately, atleast from what ive seen, You'll have to revert to 1.3.2 temporarily it seems transactions might be a bit bugged right now in the newest aseprite! It's pretty easy to go back a version see here!

I've reached out to aseprite to see if its something that changed or something might have been bugged. Will also be sifting though everything to see what I can find as well. Hopefully can get it fixed right away!
