While playing the modpack PO2, I ran into the following issue:
The quest "Leadstone jetpack" in the Delta quest line is locked, even though both the invar and conductive jetpack one are completed. The quest is a XOR type, meaning that completing either one of them should unlock the quest. I have got both completed, and the quest is still locked
I anyone knows a workaround or can contact the autors of the pack, that'd be great!
I know this is old, but I solved the jetpack problem for project ozone. It's simply that an XOR gate means you can't do both of the prerequisites to get it, you have to only do one. XOR means if there is two of the same input from both (true true, false false) there is no output. I don't know why they would design it this way but it is what it is.
