Have a ingotCobalt from tconstruct:ingot and it doesn't work in Combiner recipe for the blank data model. I have to dissolve and combine again to make it work.

There is the forge lexicon, which can convert between ingots. Not a fix but might help temporarily.

Should be fixed in 1.2.14 - All methods that previously gave tinkers cobalt ingots should now give alchemistry cobalt ingots
