Now, on a spigot server I play on with some friends, not only do they not stack, only the most recent cure has any effect at all. So if I cure the villager, I get the discount, but I cannot increase the discount by re-curing them, and if someone else cures them, my discount vanishes. We currently have the Jan 23 1.1.5 version of the plugin.

When i was talking to the server owner about it, I saw this in the error:

Caused by: java.lang.NoSuchMethodError: 'java.util.Map net.minecraft.server.v1_16_R3.Reputation.getReputations()'

Hi @JarheadHME
Which release of spigot is the server owner using?

I don't actually know offhand, but I was trying it on a local spigot server which was on the latest release from buildtools, and was having the same error.

Worth mentioning @Kasama has the error fixed in their fork here

Hi, just merged Kasama's fork into the main repo. His method is better. Just tested it and It works flawlessly.
