My human got stuck to the side of the table there on a respawn. After pulling some spiders and fighting still stuck to the table, I finally had to use Call to Qeynos to get out of there.
It isn't just short players, it happened to my high elf for about 30 seconds. Eventually it released her. I am guessing if she was shorter though I would have had to waste call home.
My froggy templar got stuck under the table too, she's not a particularly large toon and usually doesn't get stuck but there were at least 3 others that revived at the same time and that may have been what 'bumped' her under the table to get stuck, move the spawn point or the table, please.
