Hello, I have a survival server with a few friends which uses paperMC/bukkit. I already have 4 plugins that work perfectly well, but when I tried to install new ones, the green install button displayed a check mark but when I go to the server's files, the plugin isn't there. I also checked inside the game to see if it was installed, but it wasn't. After testing some things, I kind of realized that the problem only comes from plugins via spigotmc.org, the other websites work just fine. I'm trying to install a plugin called: Blood Moon.
I would really appreciate if someone could help me out because a lot of good plugins come exactly from that website and I want to make the experience on my server better overall. Thank you.
