Bugs list

Hi,
Here is a compilation of some issues I have encountered.

Matlan waterways:
- Some of the mobs in drained canals get stuck in drains (still killable)
- I can break out of animation when switching canal lever with movement (WASD) and then I get snapped back to the lever probably at the time when animation would be finished
- I have encountered invincible monkey - I couldn't highlight it or damage it but it could attack me. It was following me around and was a bit annoying. I had to lure it away and use checkpoints to leave it behind. Going to town didn't reset it's broken state. I don't have any good idea on how to reproduce that but if I remember correctly it's cage was just at the edge of ramp leading from the canal I just drained so maybe it was affected by logic that affects mobs inside the canal.

Molten vault:
- several times I had an essence spawned in the boss room. I even managed to get it once during the fight but overall I feel it shouldn't be there as it's very specific fight and it would be unobtainable after molten gold reaches it.

Skill gems:
- gems that are socketed in Hand of Chayula are not showing up in equipped gems when cutting a skill gem
- gems socketed in other gems don't seem have upgrade to their stats shown properly when upgrading their level - on several occasions I have noticed that they show upgrade from 0 to their new value instead of old to new
- Cultist warrior phantom does not show stats it's corpse explosion skill in gem details (not sure if it's intended or not)

Keep up the good work.
