[BobbyTowers]

Was it something I did wrong?

[BobbyTowers]

Never mind.

[PEMapModder]

It seems like this issue happens when a teleport request expires but the player has already quitted the server.

A possible solution is to check if player is online in TPRequestTask.

Thanks for supplying a usable crash dump.

[BobbyTowers]

You're welcome, thank you for replying.

[alicheek]

This is still happening it seems on 1.1.2

I did a quick fix in c99f97dd6262d7386acf32c3cc90f2aa59705afa. I am not sure if this completely fixes the issue.
