I had reported the teleport bug a few months ago, as I'm sure many people have... I'm not sure if it was part of this last patch or an earlier, but I'm happy to say that the time-out bug is fixed.
Before:
Someone offers you teleport. You wait a minute or two. You click accept. You are ported and get hung up indefinitely, forcing you to relog to move / do anything
After:
Someone offers you teleport. You wait a minute or two. You click accept. You get an error window saying that the teleport request has timed out.
Thank you!
