Can't use player hands but one

Some revision ago I was testing player hands. All worked fine and I went on. And next time I got an error message between two saves that it cant find a piece on a player hand and that piece was masked on my pieces window. I demasked it, saved again, and the error message disappeared on next launch. Now some revision later I noticed I cant use player hands but that particular one, and cant fix it.

There is what I tried so far:

  • I cut-pasted player hands.
  • I replaced the whole part form the previous save in the buildFile.

Any advice?

Thx in advance,

Hmm, Can’t I edit my former posts? Nevermind.

I rebuilt the hands from scratch and that solved it. Was weird though.
