If it is, this is the first time I've seen it, anyway - and I've been running Sol/Ag/Ferno + 1 team since Ag came out. Maybe I'm really that unobservant?
Abigail was taken down to zero health while Wildfire was on her. The next turn I resurrect Abigail with Sol, and Abigail returns, still on (wild)fire. By this point the enemy Ferno's been silenced and is murdered in short order; if it wasn't for the bug, there would be no wildfire present, and so no wildfire could be spread to my other barbarians. Because of this bug, wildfire gets spread to my other barbarians, stripping them of buffs and rage, and leads to my defeat.
