With this mod in Plugins folder, the game hangs on loading, stating it cannot find the .sav file for the map.  I removed the plugin through a process of trial and error, and identified it as the culprit.  The sav file *is* present, and everything works without this mod.

I haven't tried starting with only this mod so it could be an interaction with another.  But if you're having issues, could be a result of this mod.

It's had no updates in a few years, so, doubt a fix is incoming.  If anyone's maintaining it and wants more detailed info, let me know what you need.
