Ok... from what I can tell, I was able to fix this BUT it requires the replay of this last round we just went through. Only one round back, hopefully it won't be too bad for all. It does require another mod update from the mod file included in the MP SVN here. (The dll alone being updated to the mod file should be sufficient.)
So once again, take the dll from the assets file under the C2C MP SVN and place it in the C2C MP assets folder in the Mods folder then play the round.
Koshling - if you'd like, I'd invite you to take a look at the change made to confirm my (strong) suspicion as to the source of the problem - truth be told I can't seem to figure out how it's worked so far!
Also, if someone does NOT update the dll properly it may destroy the effort to fix this somehow. I need to confirm this is working so it works for all when they hit buildings with tags that perform this function!
You may be asked to recalc - you shouldn't have to with this. (Might even cause a problem in this case.)
So, ls612 is up for the groundhog day round.
