1.20.2 resource pack deleted when players switch between servers

[xPoyraz]

When players using 1.20.2 move to another server on the same network, the resource pack is deleted
but players logged in 1.20.1 and below do not have this problem, what can I do?

This is not really a Waterfall bug. Since 1.20.2 the client unloads the resource pack automatically when entering the configuration phase. It was reported to Mojang(https://bugs.mojang.com/browse/MC-265463) but they don't seem to care about it. Velocity introduced a "fix" and resends the resource pack after switching server, but this results in the client having 2 loading screens. Maybe this can be implemented in Waterfall too, although it is not really a viable solution but the best we can do at the moment I think.

@Luccboy
They deemed this as a feature request, therefore it is intended beahviour that the resource pakc gets unloaded at start of configuration phase. Its not a bug.
Feature requests are to be made on https://feedback.minecraft.net

You are absolutely right, thanks for the clarification.

We used our channels to talk to Mojang about that already (an official request still makes sense tho)

I'm perfectly fine with that mechanism. Now the servers don't have the resourcepack semiload bug anymore.

Im fine if you can modify it when switching into configuration phase, like send a packet to request resourcepack unload. It will get automatically sent by the server if not configured otherwise.

Eg. a config option would be cool.
