I am unsure what to tell you; I haven't touched this in about two years, so if it works at all in any form it's a minor miracle.

after extensive testing doesn't in multiplayer says mod mismatch.

Any plans to come back to this mod in the future? I'd like to see if the other classes could get some love.

what arcus veles suggested would be awesome

Can be made compatible with the More Town Upgrades mod? The town upgrades add more levels of abilities, beyond what this mod goes to, so they revert back to the old behaviors/etc. of the abilities once you level them up past vanilla.
