I don't have any plugins active on my sever since its supposed to be 100 percent survival for me and my friends. My latest log is 2020-12-19-1.log.gz, when I open it, its just a lot of random symbols and text.
Every time i infect and cure a zombie villager it only gives my the base rewards and is never reduced again. If i re-infect a zombie villager the trade prices stay the same. I've tested it on single player and it works fine, Idk why it doesnt work on minehut
