I hate to add to the rampant complaining in this thread but even I mostly wanted this mod to avoid using upgrades...
I do thank you both (pwnedgod and stryker) for trying to keep this mod updated but I'll wait for a fixed version with the original machines.
pwnedgod - The same gui issues that were preventing people from using zip's version. You can't pickup items in SMP with the gui open, thus making the machines almost worthless. I also was still getting it with the last version of yours I tried along with a few other issues, mostly with the textures.
