Receive this on game startup. This only happens if bz tin and lead mods are not turned on. All mods don't seem to have them listed as dependencies.

Going to add as I do not know which of your mods this is affecting, AAI Industries puts offshore pump and pipes behind research.
Research is behind burner lab, burner lab is behind stone brick, stone brick is behind water, water is behind research. Making any progress impossible.

Thanks for the feedback. I was never sure about adding support for aai-industry as it makes a lot of changes that could cause conflicts and closed loops.

Fixed crash.
Offshore pump should be unlocked.

I'm very sorry to write back so soon about the offshore pump and AAI, seems AAI changes the offshore pump to require power. If I may make a suggestion, while the AAI mod is installed why not make the offshore pump have 2 variants 1 burner and 1 electric.

For now I have removed the requirement for electricity. I may revisit this at some point in the future.

Thank you very much.
