So, this has happened to me a couple times now on different missions. The first floor of the mission is fine, no lag or anything, then I head down the first elevator. After the loading is done, I can't move, just sitting on top of the elevator panel unable to move, action, shield, or change direction. All other menus load and I am able to text in guild chat in real time without lag. I really don't know what could be causing this, it clearly isn't my internet, since I have no trouble having conversations in chat, not to mention that where I am gets a 1 Gbps connection and my current computer is on a wired connection, so latency lag shouldn't even really be possible. Usually if I wait upwards of 10+ minutes my character will rubber band around a bit and then I'll be able to proceed through the mission with maybe one or two other strange "lag" spikes where I am unable to interact with the world around me or something like that for upwards of 5 or more minutes. When I complete these "trouble" missions, no part of Haven ever gives me lag and most missions I can breeze through. However, this is the second or third mission I can remember where this strange "lag" has made me wait 10-20 minutes to start the second depth. Just wanted to post this here as it seems more like a server bug than any actual lag, hopefully it can get fixed for the future.

**Edit : So it seems that spamming items gets me out of the frozen state, this has worked a few times, that if I wait a while and then start spamming all the item hotkeys or my sprites attack keys it will activate one of them and "break me out" of the freeze, then I can continue the mission. If I hit another weird "freeze" state I can usually break out by using items and sprite attacks again after a period of patient waiting.
