Fortunately the backup I did have worked like a charm and with a few minor touchups of things I had done previously, is once again working. From a cursory overview it looks like most of the lost progress was purely visual upgrades to the base and such which shouldn't be too bad to redo. It mainly consists of redoing the proxy modeling work. So it looks like this week I will be poking at that a bit and trying to finish off the player's concept painting.
Thanks for the patience! - CJ
