[Teine]

Logged in today to this problem, Have taken a break recently so first time I have logged in for a bit. Had it happen twice today, tried the log out and back in with no change.

High Elf/Paladin
Leth Nurae Crafting Area, Right by the outdoor Forge (Leth Nurae -25,26)
LOC Approx. 74,-75657,65368
I camped out when I last played, but after I got disconnected I also found myself in this position. I used /stuck to get myself out so you should be able to check log files for that.
No alternate form in use either time.
No Mount.
Logged out by the forge, in fact when I find myself in the world I have logged out sitting on a pathway or a raised portion in the city.
No levitation.

Most times this has happened I have been crafting and logged out in the crafting area. I did log out and back in a few times today and I went and sat on normal ground, when coming back into the world I was fine, standing on the ground.

I will test this next few times I log and check to see if sitting on flat ground as opposed to sitting on a pathway changes how I spawn in world on log in.
