sometimes "tp" button doesnt work.

Hi, i have f5 set to cast a tp for me, it does not always work.
sometimes it says "you can not get there from here" but its just a map,
and my last location was my hideout. so i manually open tps.

the problem is that if I login and it happens once, it always happens.

is there a trick to resetting this situation?

i could try switching servers... havnt tried that yet but why would that help?

thanks.
