I noticed you put my name in the changes for 0.7.4 as well as 0.7.5 in regards to Sodium Hydroxide.

But in 0.7.5 it is broken. See screenshot:

For some reason, you've got it under Angel's, which isn't what I was asking for.
The following need to be included:
sodium-hydroxide
cobalt-steel-gear-wheel
cobalt-steel-bearing
silicon-nitride

I've added back sodium-hydroxide, silicon-nitride. It's really cumbersome that Bob's only and Angel have all these small differences... Cobalt-steel intermediaries should work already, they are added further down in a loop.
