[suggestion] upgrades for harvester
how about getting the possibility at lvl [x] to upgrade even the harvester?
Upgrades could things like:
SUSPICION: when getting in Range XX of the harvester, it stops walking, not to show raiders the path
AMBUSH: when getting in Range XX of the harvester, it can go alternative paths to lure raiders into deathtraps
GEN-MAT BRAKE: the harvester just don't walk, he sits at the start, waiting raiders getting busted
INSTABLE LOAD: when getting killed, the backpack of the harvester explodes
good raids custodians
