I’ve noticed two cases where “End Turn” is suggested, replacing the AP diamond, despite board matches being possible.
I’m playing with battle style set to AP and with “auto end turn” disabled.
. Gem converters
There were no matches on the board, so “End turn” was correct for a bit. But then I used a gem converter, setting up new possible matches. The diamond should flip back to AP. Example video (Sunburst)
. Gem destroyers
The AP counter changed to “end turn” when a spell destroyed a large number of gems, but didn’t change back when new gems fell from the sky into matchable positions. Example video (Ice Storm)
This happens most often with effects that destroy (or remove?) large numbers of gems. I’ve seen it with Ice Storm, Lightning Bolt, and the Mercenary’s greed gems. But it doesn’t happen every time due to depending on what is destroyed and what new gems fall down.
