Dragonian rogue not exploding gems

Platform, device version and operating system:
Latest version on Android (Samsung galaxy S8).

What you were expecting to happen, and what actually happened:
Description of ability says it destroys gems in an X shape and does damage boosted by purple gems. It is making me select a single gem and only exploding that gem.

How often does this happen? When did it begin happening?
I don’t know how long or often this has been happening, I just started using my dragon team for a task and noticed the bug, after having not used it for a while (up to several weeks).

Steps to make it happen again
Just use dragonian rogue

Dragonian Rogue does not explode anything; it destroys things. Pick any gem and it destroys gems in a gigantic X shape, with the center being the gem you picked. I just tried it and it’s working fine for me.

Explode was the wrong word, I meant destroy. I thought I recalled it destroying 3 rows of gems in an x shape from the centre of the board.

Hey, Dragonian Rogue destroys Gems in an X shape to the edge of the board. I tested it and it appears to be working as intended.
