This doesn't sound like it contains any script modification at all. Or does anything useful. The 1.66 may simply work unmodified and without complaint. Unless someone gets an in-game warning running the 1.66 version, there may not be anything I need to do, and since "server messaging" is a banned spyware functionality, it may as well STAY broken as far as I'm concerned.
Just thought I'd let you know that I am indeed getting a warning about awesome. I updated all of my mods to 1.66 (twallans mods didn't need updating past that; they still work fine) and loaded the game. Everything worked fine. I pulled all of my mods out (to make sure it wasn't a conflict), installed awesome, and got this:
It can't be a framework issue or anything, as I've been running awesome for... what, 6, 7 months now, with no issues at all. This just started when I patched my game to 1.67. Anyway, yeah. Just thought I'd let you know that for me at least, there does seem to be an incompatibility issue between the 1.66 version of awesome and the 1.67 patch.
