Note: TFC version 3.2.14

Ok so a wierd glitch has shown up after updating Terrafirmacraft along with some other mods, and forge, for my custom modpack (Accessible publicly on technic under the name Halsion Reach: Primeval): Pickaxes, regardless of tier, seemingly, are unable to mine blocks. This affects both me and one of my players on the server I run, and the only thing that's been changes is that TFC got updated from version 3.2.4 to 3.2.14.

Under Jade, the effective tool level indicator is also missing.

This means your modpack broke item tags. Not a TFC issue

I forgot about this issue ticket... Turns out that the addon for TFC, TFC Metallurgy, has the tags broken; Without the mod added, all pickaxes work, and adding the mod back in breaks them again, though adding LMFT also fixes the tags.

Ended up learning that a couple of days after I opened the issue.
