So I'm loving these iso vaults but here are some issues I'm encountering: Stability and crashes out of the mission. I've lost quite a bit of loot over this holiday weekend due to this. I like that these missions go so long and deep but that may be part of the problem. If one plays all three tiers and does all the arcana missions there are plenty of ways and times to crash out and lose you're stuff. This also makes it near impossible to reach T3, and it becomes quite a gamble. Please work on stability on these vaults.
