There's something seriously wrong with void horrors

I think it must have triggered a major anomaly

talents/chronomancy/anomalies.lua has this line in the action block of Anomaly Sphere of Destruction:
local tg = self:getTalentTarget(t)

However, the "tg" variable is not used anywhere else in the talent definition. This might just be a superfluous line of code that was copied from another talent, but it makes me suspicious. Other than that, I don't see anything obvious.

No, this was Blazing Fire.
I've checked these and I can't see anything wrong with them.
All I can think of is that something is going wrong with the damage calculation due to the actor being dead.

Maybe some value of the void horror (such as paradox) is read, but since the void horror is detected, something nonsensical (infinity, NaN) is returned and erroneously fed into damage calculations?
