TMI is unable to display all the blocks/items corectly in SMP due to the way IC uses to conserve Block ID/Item ID usage. They're still there, you just can't cheat them as easily.
As for the machines not crafting, can you give a specific and non-TMIed example?
thanks for the info about TMI, that was starting to drive me nuts.
Yes I can, i just tried several of the recipes and alot do work like you said, although only one of the generator recipes and only one of the iron furnaces work. although i believe i read somewhere that that is sometimes expected so im not worried about those. specifically some of the ones i tried that do not work are. extractor, macerator, canning machine, solor panel. i crafted each piece with the best i could without using TMI. when i place the items in the crafting bench there is nothing on the output. its really weird.
