Agnostic Barbarian Rogue KOS to Treants
 

I'm just curious if this is classic before I submit a bug report. Doesn't seem to make much sense.

Can't tell you for sure if it's intentional or not, but I'm 90% sure it's because you're a rogue, not because of your race or religion - friend's dwarf rogue had the same issue. Trixy devils aren't welcome around the druid rings apparently.
