Information

• I have provided as much information as possible

I'm also affected by this issue in version FTB Neotech 1.10.1 (released April 6, 2025). The crash happens consistently when using the Mining Hammer (from a quest reward) to break blocks.

Crash:
java.lang.NoSuchMethodError: 'int pro.mikey.justhammers.neoforge.HammersPlatformImpl.getBlockXpAmount(...)'

It completely breaks progression in the modpack, since the hammer is required for strip mining and is tied to quests. Please consider fixing or temporarily disabling the XP output call if unused.

Tested with clean install via CurseForge launcher, no Optifine or external mods installed.
