i created a destination portal in world 1 then i created a portal in world 2 with destenation world1.

when i move anywhere on anymap i fly up and i cant stop have to reboot server ?

Try deleting the portal file and remake the portals, could be you selected a giant region by mistake. If the problem persists ill take a look into it as it is probably a bug.

I will assume the problem has been solved due to no reply, crash logs or enough info to replicate the problem. If the problem persists then just comment and ill reopen the issue.

I am having this problem too :/
