there seems to be a bug with the compatibility of project red and thermal expansion .. the pipes part of project red, If I craft something in a Thermal expansion machine using the crafting pipe from project red it crashes my client.

Under the same case as #447.

Is it a crash or a freeze? The freeze is #447, but a crash may be something else. Freeze happens because crafting pipes Just Don't Work™.

I tried smelting 8 sand in an Electric furnace but it crashes as soon as I request the 8 glass .. So I don't think that its because the inventory of the machine cannot accept more than 64.

Well, My computer is kinda crappy so I think it just couldn't handle the stuff that was going on and it decided to stop the game .. Anyways from what I understood MrTJP isn't going to fix it because he stopped the development for 1.6 ?

No logs, no assistance. Will be fixed in 1.7.
