Bugs with a second dungeon.

[archmag]

Tried second dungeon for the first time. Completed a set of first 5 rooms with 60% rate (did two of them successfully) and destroyed only 2 or 3 stone altars. Fought some mummy on the left in the boss room but it never moved, just stayed in the corner (first issue). Got loot roll. Attacked the ghost snake in the center which had shield effect on it. Eventually killed it doing 10 damage per hit with my bow. After looting everything activated another loot roll that appeared and the game froze (second issue). Checked the wiki and apparently I wasn't supposed to be able to fight with the snake if I had only 60% completion and didn't destroy all altars (third issue).
