hey, I just installed 1.9c to a modpack I downloaded today ( https://www.curseforge.com/minecraft/modpacks/minecraft-eternal , however I also added crossroads and its dependency, essentials.) I am getting a crash on startup, apparently because the Thermal expansion/ Dungeon tactics integration is having issues with the iron club. The modpack does include both mentioned mods. The log has this to say:

I turned off TE integration in the dungeon tactics config (in the mia folder), and am now trying to start the game again. So many mods, it may take a minute...
Edit: That worked! So it's just a problem with the TE / DT integration module apparently. Now to enjoy :D

Hmm... I think I see what the issue is. The modpack you're using must be using a little outdated version of Dungeon Tactics. The version 0.16.7 added new features, block, items, etc. which I'm accessing. Thankfully, you were able to disable the integration, which helped with the issue.

I'll look into automatically disabling the integrations that are cause issues, so this should make using my mod more convenient.

Should be fixed by 1a43d5c
