"Unable to leave area" .. What Is This?

[Pintsized]

If you had read my post carefully you'd see this is NOT a case of sever queues which is what your link is all about, this seems to be a housing instance problem, as StouterTaru noted.

Location/Region you are in: (actual location such as state, not in-game)
UK

Wired or Wireless Connection:
Wired

Does the issue occur at a specific time frame/interval or day?
No. Note this is NOT related to login queue size, as I reported above the login queue in Phoenix while this was happening was only 41

Does it occur with a specific character or all characters?
All

Does it always occur in a specific area or instance in the game?
It seems to be only in a housing area instance when trying to enter a house

Server that issue is occurring on:
Phoenix

Internet Service Provider:
Virgin Media and BT

People are in their houses/apartments/etc using up all the instances, so they can afk macro hop without being obvious.

Nail firmly hit on head.
