Hiya wonderful Spine people!
I think I encountered an unexpected behaviour in the latest Ps to Spine script 7.31.
I was exporting from a Ps with the following issue:
There's 2 times a [merge] layer called l_arm. One of them was supposed to be an r_arm but the artist missed it.
The Ps to Spine script exports everything without complaining, with the result of having one PNG called l_arm which is a right arm, and not r_arm at all.
Maybe the script fails to spot them because they're [merge] layers?
