Alchemist dying when stairscumming?

[mwmw]

I was in the Lake of Nur trying to beat the Weirdling Beast. I had to stairscum a couple of times. On the last time, I noticed that I had tons of undistributed points, so I decided to put them in. After going back up the stairs again, my alchemist disappeared. As in completely gone. All I had was my golem. In addition, I couldn't make my golem go downstairs. The game wouldn't let me swap over to my alchemist even though it said that the line-of-sight between my golem and the alchemist was broken. I tried to attack the Weirdling Beast, but my golem died (of course) and I got sent to the Eidolon Plane.

I was filming the whole thing, so I saved it in really low quality (to speed things up a little). There's a small but obvious break in the middle; that's when I was busy mashing everything I could think of in an attempt to resurrect my alchemist. Apparently, chatting was disabled while my alchemist was gone. Strange.
