Server shut down during Labyrinth's final boss

Doing Labyrinth for the first time with a new build on Merciless.

Finding the keys for 2 golden doors.

Managing to cut most of the boss' mechanisms for the later fights.

Getting to the boss' last fight.

Server shutting down during the fight.

F*** me, right?

Here's a suggestion for you GGG, to lessen the frustration of having wasted 30-40 minutes :

Allow the players to save their frigging progression in Labyrinth. Like, a temporary waypoint in the Aspirant's Trial room before every boss fight.

Pretty please.

With sugar on top.
