Emrakul Ability Bug
Emrakul, the Exigent Doom seems to bug out the game/server when her mana ability is copied onto different lands after those lands are used.
I found this using Peter Parker's Camera and Emrakul in standard.
Activate Emrakul's ability exile her and then copy the ability onto another land, afterwards use that land for mana to cast something else and the game state seems to freeze entirely.
I'm not sure if Ugin plays a part in this but I did have an Ugin on the board in both cases.
