Crash issue when used alongside bluemap

[ItzzByc]

Basically this mod makes bluemap not work and crash the server everytime it tries to boot up. I checked every other mod and its just this one the one that crashes it.

I need the crash report please.

Also what game version and modloader is this on

[ItzzByc]

game

1.21.1 Neoforge 21.1.228
There isnt a crash report being made in the folder so yeah I really cant find it.

Your latest.log should also contain the crash information, so that can work as well

This one shows only Bluemap being installed.

Weird, I checked the latest logs and crash logs and no one shows the part where bluemap crashed.

Btw until this is fixed i have downgraded to these and my server started. ( not setup yet so dont know if it fully works )

SimpleDiscordLink-Universal-3.3.1.jar
CraterLib-NeoForge-1.21-2.1.5.jar

I still have to confirm in my own testing, but the issue appears to be coming from their side

The main issue is how they repackage Adventure. We changed the way we do it, to the recommended way of the modloader because we also use the library on other platforms (paper and hytale).

So in order for us to fix this on our side, I would need to revert our entire setup, which will also break a ton of things for us.

(I still hate this stupid system from forge and neoforge.....)

Okay so this gets interesting.

I am not able to reproduce this crash with either Bluemap, or Bluemap and Xaero's World Map

So if either of you have a modpack link I can test this with, I can continue the investigation further
