is a known and solved issue, see the first pagemexmer wrote: Sun Mar 10, 2019 11:32 am boblogistic has some unprecedented shortcuts in research
as you can see, T1 fast inserter techology (exists in vanilla), unlocks in boblogistic express inserters (which are t3), so even if you research them, until you get to blue technology, you cannot make them, not to mention they need as component T2 inserters (which you don't have researched at T1)
stack inserter technology is dependant on fast inserter technology, but in context of what i wrote above, it doesn't make sense either.
I'll look into it, but it's possible I already solved it and forgot about it.mexmer wrote: Sun Mar 10, 2019 11:32 am also logistic 3 - which unlocks t3 inserters and belts is locked behind production science
for both screenshots i used following mod config
