Versions:

• This mod: 1.25.5-957
• Minecraft: 1.21.11
• Mod loader version: NeoForge 21.11.38

Other Mods: (all are latest as of 3/17/26)

• Common Capabilities 2.9.7-330
• Integrated Dynamics 1.24.1-1662
• Integrated Tunnels 1.8.30-608
• Integrated Terminals 1.6.6-738
• Curios API 14.0.0
• Sophisticated Core 1.4.9.1527
• Sophisticated Backpacks 3.25.37.1587

Common thru Tunnels just needed as dependencies, Terminals is the one that adds the breaking behavior.
Sophisticated Core/Backpacks (from what I can tell from testing) is only really needed as a mod that registers a curio slot. My guess is that this could be substituted for any mod that does the same, but I haven't tested that. The crash did not occur without adding them in though.
