A few problems

I mnoticed a few problems with the game. The illuminated decoys and the medical arachnids are not working. I am using the Kruppstockfixes from the terra-arcanum site, but they do not work. Also I cannot build an automaton gunner. I have the schematic and the required components in my inventory, but when I click the build button nothing happens. Please help!

 

Does this belong here, or in Arcanum Tips, Hints, n' Strategies?

I have mixed thoughts about it.
