Lategame in a 2.1 Bob's + Angels run. Hydrazine generated seems to expect "Hydrazine" but all fluid recipes connect to "Hydrazine gas". The Factoriopedia entry for "Hydrazine" is a stub with no recipe or unlock tech, only saying that it can be consumed in the hydrazine generator. Attempting to connect "Hydrazine gas" to the generator results in a mixed fluids warning, and no power generated.
Seems like a simple rename? Haven't tried modding myself or I'd try to point out the line and help more!
EDIT - I'm running version 3.0.0 of Bob's Power mod, just to confirm that.
