I don’t think removing stud harvest is a solution because you can place a distrupter and it can disable zombie spawn point at won location for an example like the bridge it easily can get shed farmed there to
Shed Farming is a symptomatic issue of the root problems: a poorly made spawning system, and the game's repetitive, grind-intensive progression. You've just looked into the problem in the most shallow way possible, which is incredibly dangerous. Fixing the symptomatic issues never leads to the root being tackled, but rather forces the community to find an alternative, untreated symptomatic issue. You cannot simply fix the root by getting rid of all the symptoms. Players will find more.
