Something I'd try right off the bat - try a different CC than Singular. Any time you have a problem with combat of any time (not targeting, no attacking, wrong selection... basically doing anything incorrectly that has to to with combat), try a different CC and see how that effects it.
Just to to this folder: Druid and select one. I use FPSWare Druid but I'm not using Balance so I can't say how well it would work. FPSware hasn't been active on the forum for more than a month, but we're still hopeful that he's coming back.
Try that and let us know how it works... good or bad and post a new log if you're still having problems.
