Could not get provider type for dimension X, does not exist

[Sir-Will]

hey,

I moved my 1.7 servers behind travertine and now some players are getting "Could not get provider type for dimension X, does not exist" for skyblock servers where they are not in the main world but in a plugin created world.

You need to provide information about your setup so that we can actually attempt to replicate this and look into it.

I'm unable to reproduce this issue myself but getting a lot of reports from players having this issue. One said the issue is back once the server did restart. (Moving them to the spawn temp fixes it).

This happens on a forge cauldron server in bukkit plugin created worlds (uSkyBlock, Multiworld..).

This is the full crash report: https://pastebin.com/eeQ7Q6cU

This is what shows up on the server:

Reverted to previous version and the issue is gone, so travertine seems to do something different here.

Hi, we are facing the same issue on our server. We are running Thermos 1.7.10 on our backend servers. When you join a Bukkit dimension, Thermos sends DimensionRegister packet to client to inform it about the world's provider.

https://github.com/CyberdyneCC/Thermos/blob/bae97f16f0fac984a56083769ef75cb8a8eb1812/patches/net/minecraft/server/management/ServerConfigurationManager.java.patch#L114

I think that either the DimensionRegister packet doesn't get forwarded to the client at all, or sometimes the client receives the Respawn packet before the DimensionRegister and that causes client crash.

Sometimes it seems like the DimensionRegister packet doesn't get forwarded:

But sometimes, it does:
