Heyo! It appears that a specifc combo of some of the recomended mods throw a tech loop error:

Failed to load mods: Cycle in technology tree detected.

copper-processing
-> automation-science-pack
-> manganese-smelting
-> bismanol
-> electricity
-> copper-processing

This happens when the following mods are ALL present in the same list:
- Manganese
- Bismuth
- BZ's Aluminum
- K2
- SE

If any of the 5 mods are taken out, then the error is no longer given.

Taking a look at the code, it appears that Manganese (specifically, Bismanol) is the culprit. I cut out the following from bismonal.lua:

if mods["aai-industry"] then
util.add_prerequisite("electricity", "bismanol")
util.add_ingredient("electric-motor","bismanol", 1)
else
util.add_prerequisite("electric-engine", "bismanol")
util.add_ingredient("electric-engine-unit","bismanol", 1)
end

The game then loads fine, but there doesn't seem to be any use for Bismonal. Dunno if that's my fault or it's simly not implemented yet.

That would Indeed remove all uses for bismanol
Will have to see what causes this

Should be fixed now in the manganese update!
