My team: 4x Doom of Stone  
Defense: Living Quartz, 3x Doom of Stone

Sometimes, the board will get stuck after combining skulls. No moves can be made. It’s triggering Living Quartz’ Mana Potion trait, so guess that’s related.

My wild guess would be this lockup happens whenever the Stone Fragment trait picks one of the still resolving skulls to transform into a brown mana potion.

If it happens on fresh start with Doom on loading screen, and does not happen until restart after Living Quartz shows there, then it is likely this one: [[Investigating] Game Freeze in Training](https://community.gemsofwar.com/t/investigating-game-freeze-in-training/70214)

If you are on Windows, check if `Player.log` in `%userprofile%\AppData\LocalLow\Pipeworks\GemsofWar` contains something like

```
NullReferenceException: Object reference not set to an instance of an object.
