http://i.imgur.com/GiQqh4p.jpg is it possible to make it looking for "material.wood.display" in Tinkers Construct .lang file instead of material.wood? For all materials of course 😄

I changed that to use the display name of the part in 1.1.11b, so it should show the same name as the part itself (see: https://github.com/squeek502/TiC-Tooltips/blob/1.7.10/java/squeek/tictooltips/TooltipHandler.java#L640-L641).

However, the linked code doesn't seem to work right with ExtraTiC (#21), so I'll probably have to revise it anyway.

Is the name of an actual wooden part different from what it shows in that tooltip?

Yes, it is wood part but should be wooden.

Still a problem...

I meant to ask: Does the wooden pickaxe head item itself show as "Wood Pickaxe Head" in default Tinkers Construct? I just checked, and it does. Therefore, this is a Tinkers Construct bug.
