thank you for your replies. Unfortunately only error i get from GMS is at import saying its wrong spine version, cehck compiler for errors (shows none).
However, the same spine file i have other skeletons. All of them uses the same skeleton exported from original skeleton (which has the problem json)
HOWEVER, any exports from the other skeleton in the same spine file and version imports properly into game maker. Though, the original images used on those are somehwat smaller than the first problem one. So for some reason, the problem only exists in the first/original rig.
Ive only tried posting in forum, ill try contacting GMS directly. I just didnt know if this was a spine thing or GMS's issue. If the original images have to be smaller then ill have to make sure they arent too big, because the later ones work in GMS despite being exported from same spine file. ill come back if i get more info from GMS.
ok so found out issue with the later ones, just had to fix some issues with some erroneous keyed frames.
