birchmonkey: conveyors splitting will split every other item in x-lines = x-share_of_items. this means if there are two lines splitting from a conveyor on a given tile, every other resource will split onto each line. HOWEVER, the order in which items split (which resource goes first like garbage vs plastic or electronics) is decided by clockwise priority. it gets really wierd but there's a thing in the help section I think? ALSO, a lot of inconsistency related to it has to do with a wierd behavior when adding a split while two or more resources are traveling on that conveyor belt. if you time it right, you can delete just the first resource and effectively reverse the order of splitting. Beware though, if you do this and clear tracks ever it will return to normal and youll end up with garbage piling up at your sellers.
