Start with mage/abilities/TriggeredAbilities.java at lines 163, 166, and 117, then trace the event path through GameState and GameImpl shown in the stack trace. Reproduce the server game error with the reported versions if possible; done means the NullPointerException no longer occurs in this path and the failure is covered by a regression test.
