Conversation
On Paper 26.3 every BuildSystem menu item with a player head failed and /worlds threw "Unhandled exception executing command". XSeries 13.7.1 links com.mojang.authlib.minecraft.MinecraftSessionService in the ProfilesCore static initialiser; 26.3's authlib replaced it with SessionService, so the class never initialises. XSeries 14.0.0 is the 26.3 release and resolves the new session service.

Problem
On the stage buildserver (0.7.0, Paper 26.3) every BuildSystem menu fails:
