Hmmm, did I ever upload 1.1.2?
It says 1.1.2 in my signature, but there is none in the sourceforge folder. It's also not been tagged in SVN, and no branch either. And all the issues against it are closed.
It's been a long while since I've worked on this...
None of the closed issues sound like they would make an edit crash the game though, so there shouldn't be a reason to not work with 1.1.1.
