Using Blender 2.8. Some animations are also repeated/broken.

Would you be able to share an example .blend file? You can attach ZIP archives to GitHub comments. Thanks!

I forgot to mention that I'm using Blender 2.8 and I'm trying to export to a Game Engine (Godot).
Thank you.
FWIW: I just figured out an issue with inverse bind matrices (they did not take the mesh object xform into account). Working on a PR - this may help :)
PR #280
Doesn't seem to solve everything though :(
I believe this to be very related to my issue here: https://github.com/KhronosGroup/glTF-Blender-IO/issues/232
@setpixel would you be able to test whether #280 fixes the issue?
@donmccurdy checking now!
Hmm - no it doesn't seem to fix it.

Ok thanks for checking! Looks like there are additional issues.
I think the issue is around the skin order
Initially exporting I see this error:

That's not the core issue here (there's stuff to fix in the skinning export, for sure) but want to not lose track of it.
This is now solved
