I could not cast the power in the situation shown in the image below.
there was an invis tile at the beginning of the turn, which got destroyed being included in a match5+ caused by scarlets CD tile.
Fireing another power (visions) did not help, could not cast power in same turn.
ability button simply did nothing, no warnings or such
Did you invis.. then get the match 5, which will cause timers to go down, popping sw’s and removing invis?
It may think it is still the same turn, in which this would make it a bug, as the match 5 ends one turn, and starts a 2nd technically.
Side note, since he is not working for you, i will gladly take him off your hands 
Invis was existing before, the match5 was caused by Scarlets Countdown tile, which destroyed the existing one
