I'd strongly recommend everybody who is annoyed by this and has not already lost his temple win streak to not participate in any contest, spend any stamina (so you can't get a new temple) and particularly buy no diamonds or packages until this problem is resolved.
Gree has broken the crypt (was it really an accident or just to limit gold flow into the game???), now they ruin the temple by this ridiculous bug, making connon fodder minions into instant super killers. Or is it a bug? Call me paranoid, but hopefully it will be fixed in days, not months (like the crypt).
As people are getting quite annoyed about this new surprise, please comment, @DSKenshirou_X .
