Collectible Card Game Headquarters

At the end of my turn, the AI tries to activate Eye of Ugin. It sacked a few Spawns to pay for its activation, but now it is stuck. As in: I can't even click in the program itself to bring up the context menu, and as such I can't make a dump. It seems to be stuck in a loop trying to do something, but I don't know what since it's not resolving. After the initial screenshot (EoU_stuck), it presented me with the error shown in the second screenshot (EoU_error).

I literally have no idea what is going on...

I can't replicate the bug. I saw AI few times not be able to sac the mana token while paying mana to activate Eye of Ugin and so wasting the mana of that turn but no stuck/loop or error. Without a savegame which is generated every turn at the beginning of each turn = AUTOSAVE.(ending according to what type of game you play) I can't do much else. Please next time attach a savegame.
