BetterAdvancements-1.12.2-0.0.11.56
Triumph-1.12.2-3.0.1

I'm making a modpack with Triumph/BetterAdvancements that works perfectly in singleplayer, but when testers open the advancements tab while playing on a server they instantly CTD.

If they create a singleplayer world first, then join the server they can open the advancements window normally for a while before crashing again.

Put your crash log on Pastebin, Hastebin, Github Gist, etc.

@Blargerist this looks like something for you

Should be fixed in 3.0.2 (Waiting for approval on CurseForge.). For future issues, please use the Triumph issue tracker or pop into our Discord server (Link is on our CurseForge page).

Issue can now be closed.
