Just wanted to say thanks for this mod.
I was using v 2.6, which stopped working recently. I did upgrades of my forum from 2.0.11>2.0.12>2.0.13>2.0.14>2.0.15 , then uninstalled the Maps mod (leaving Remove data unchecked - the scary bit). Installed v3 of the mod - and it's all back and working, with all user data still there. Phew. Cheers!
