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.
Just to add on to the string of two year late replies, you can manually change the requirements. Open the file location through CurseForge, then navigate to: /saves/[your_world_name]/config/betterquesting/Quest Database.json. Scroll down to the quest (#252 to unlock Conductive or #246 for Leadstone), about halfway down the file and simply change the "Quest Logic" variable from "XOR" to "OR". The next time you launch your world, you'll see both jetpack progression lines unlocked.
I'm 90% sure of the file name, but I'm writing this on my phone and purely from memory so it may be wrong. Just pick the betterquesting file that refers to the quests with words and not numeric addresses.
