+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.
+
+This patch has been removed, as MC-181190 was fixed by mojang in 23w31a.
