Cool thanks. Upgrading fixed it, other than giving me new fun issues with Neko I didn't have prior. That also doesn't really explain why it worked right up until it suddenly stopped working; it also doesn't really explain why now Neko has issues it did not before.
Thanks to everyone on the forum for helping me.
Unfortunately, I think I'm going to stop trying with this. I keep running into issues and can't tell if it's the IDE, not having installed something correctly despite receiving no errors when installing, or syntax errors. Syntax errors I can at least eventually puzzle out, but the other two are pretty exhausting, and every day has felt like I'm fighting to get anything done.
I get there are growing pains with any new environment, but I'm just tired. I want to be spending the little time off I have actually making my game. You guys have some sweet documentation and when things work, it's a pretty sweet set of libraries.
