Lost my temper once in Dusk Vigil. Was playing AST back when it's cards had different effects, when I accidentally used an Ewer on the tank, was probably just trying to use it somewhere to get rid of it.
The tank then stopped, and proceeded to give me a lecture into the different card effects, just stopped the dungeon run while we all waited for him. Super patronising, and disruptive for all three of us.
I lost my patience and lashed out, kinda surprised I didn't get reported for it to be honest, given my choice of words. The rest of the run was dead silent.
