When I updated ngt1.5.2 to the latest version, all items from MPS became "Unnamed", became uncraftable and ceased to function. I tried disabling MPSA but it didn't help. Since I wasn't in a fix-it mood at the time, I just reverted to the previous version of the ngt pack, where everything was working fine.
(Disclaimer: I haven't looked into this problem thoroughly, so my apologies if there's an obvious and well-documented fix. I only wanted to mention it while it was on my mind, in the likelihood that I forget to later.)
