question

[Katy]

isn't the winter festival enhancer supposed to be running for four hours? i thought it was.. if not that's okay. but i just wanted to know because when i left the winter festival dungeon the enhancer stopped running and still was at the four hour mark. is this a bug?

The ticket/elixir works for either 4hrs or as soon as the boss is killed. If you join a nearly completed map and the boss is killed as soon as you join that's it. It's safer to host your own game and buy as you make. That way you can also lock it &/or invite friends.
Edit - sorry I couldn't see on the mobile app that this was in S. L. , my answer may only apply to P. L.

so it stops when you leave the dungeon? thought so
