Client Crashing on World Change

Hey, for some reason whenever I teleport my player into another world, he crashes.

PM Version:

Code:

PocketMine-MP 1.6dev-1266 「[REDACTED]」 implementing API version 1.13.1 for Minecraft: PE v0.13.1 alpha 

Client Version:

Code:

0.13.1

any ideas?

Use pocketmine bleeding builds or ImagicalMine

cant get any pocketmine phars. all their jenkins servers are down

nope, ImagicalMine's Jenkins working! http://jenkins.imagicalcorp.ml:8080/job/ImagicalMine/

i meant pocketmine's jemkins lol

Go to the pocketmine repository download the src folder, compile it or just put it in your server

Sir, are you a bit too outdated? PocketMine has already been merged into master. No more bleeding builds.

Ooops... I should not only look at the ImagicalMine repo
Ok, but the jenkins server is down anyways
Thats bad
Does anyone know why it is down?

Use the alt URL at http://www.pocketmine.net/api/?channel=development

But that is only the last dev build and not the last compiled build from github

Have you confirmed that it happens on all worlds, any worlds?

No, if a player teleports from a world that they joined the game in, it wont crash. But teleporting back out would make the client crash. Also for some reason I [sometimes] crash when joining the server. Any ideas?

I suspect this has something to do with something like this. https://github.com/PocketMine/PocketMine-MP/issues/1098 (this is a client issue)
I don't know the exact reason. Have you tested if that happens on a clean server, with the original map completely clean, like superflat without any entities, etc.?
I don't know how to understand client crashes, so I can't help with this. (Too lazy to reproduce this bug anyway) I'll notify the PocketMine Team on this.

Ill have a check, but yes i think it has something to do with entities. Also that issue was made 2 years ago xD

Yes, I know, it was already fixed, but I suspect that something like that is happening again.
