I'm 99.9% sure this is a thermal issue and not a KJS issue,
unfortunately it seems like the arboreal extractor itself short circuits when checking what tree it's extracting from.
from what I can tell:
- it checks the type of log first,
- then if there's a recipe for that log and the leaf that is attached,
- then if the leaf is natural
- might check this before the recipe, idk.. not important..
- then completely disregards what kind of leaf it is and picks the first recipe that uses that log.
- (first recipe that isn't hard coded)
- I figured this out because I accidentally made oak trees produce sap instead of resin, and then every oak tree produced sap.
seems like the devs of thermal didn't expect people to want to add other trees to the arboreal extractor..
