Merge branch 'celestialCircle_fix' into 'master'

Celestial Surge Bugfix

Celestial Surge for some reason requires an actor to stand at the center of the circle for it to deal damage, even if there are other actors in the circle. This removes that requirement so that all circles always "detonate" properly.

Also assigns the "circle" subtype to the Surging Circles buff, because it looked sad and lonely without one.

**This MR is save safe.**
