The ones listed as [Done], if i do them again, they do not trigger resources in home village being gathered.
The ones labeled as repeatable do trigger resources in home village being gathered, but each time they are done, difficulty is increased, i am currently lv 20 and difficulty 4 wipes out my characters in a single enemy turn, and the resources being gathered are not necessary the ones needed for upgrades in village. No idea how high the increased difficulty goes, but there should be a limit to it so people will not get stuck.
