Pets don't like Seawall tiles?

[cat]

Had a weird bug, was not able to reproduce it but when moving with pets to a Seawall tile at 24,24 Purg my Elementalist pets stayed behind on the last tile, they were viewable as a group of pets, my pets pane said (0), and when I moved back to the tile they were on they "rejoined" me.
There was another character present on the Seawall at the time and that factor may be part of the bug and why I wasn't able to reproduce after when they had left the tile, I'm unsure.

This is almost certainly a result of pet tick lag. There are some changes in the next bug that should help address it.

I can't think of any reason why Seawall tiles would have a special impact. This tile type is mentioned zero places in all the codebase.
