Invalid Target?

[Pure Lunacy]

I apologize in advance if this has been brought up but has anyone else got an "invalid target" message when using Wild Growth occasionally? I was wondering if it was a known bug or whatnot. ???

I get that message when using Wild Growth during the vortex on the Malygos encounter, GM stated it will be fixed, other than that I've never seen that message.

I've seen it there too, but targeting yourself usually works.

I had the error message "Invalid Target" too, when i was running gundrak hero with my friends. Maybe is bugged :V
