I'm currently running a spigot server over aternos, with no mods. Just for a few more commands like /tps or something. Yesterday I joined the server, but no mob was spawning. But I don't have changed anything in my options since 2 weeks. The server is on hard and I tried /gameruledoMobSpawning true and checked bukkit.yml but all is like as prescribed on the wiki. Can someone help me improving mobspawning on my server without deleting my world?
Btw I restarted the server already
