It must be frustrating to have this much work done and having this issue.
I am not arguing the point – just stating that to my knowledge no mods have been completed and made stable to run in game that have altered more than just the class name in the strings of the atlas/skel files. Unless they are using Spine.
Frustratingly killthemall changed something other than the class name and it worked perfectly while we were still using the leper class name. When we changed the class name that’s when the problems occurred (although not necessarily because of changing the class name, maybe something else changed too).
So about Spine… What was the minimum price tag for a working version that would allow us to save the game files again? And, more importantly, how likely would either of us be to use it again for other projects in the future?
