Instead of completely resetting a Villager's reputation for all players each time they are cured, we now only reset the relevant part of the reputation for only that player. This means the exploit is fixed and players cannot stack multiple cures until prices are down to 1, but doesn't have the same side effects that are commonly complained about with the current exploit fix.

Subject: [PATCH] Fix curing zombie villager discount exploit
|
|
|
|
This fixes the exploit used to gain absurd trading discounts with infecting
|
|
and curing a villager on repeat by simply resetting the relevant part of
|
|
the reputation when it is cured.
