ExtraTiC seems to cause some discrepancies with the built-in compatibility in Tinker's Construct for Thermal Foundation.
I cannot repair any tools with the Shiny material, which is from Thermal Foundation. Attempting to repair tools made with this material will not work, as the tool forge will not show the repaired tool.
I checked by removing ExtraTiC, and the repair worked normally that time.
This may be linked to the fact that the Metallurgy Platinum, when melted down and casted, turns into Shiny tool parts.
However, I'm not the maker of these mods, so the reason for the issue may be completely different.
Any help on this situation?
