Question No mobs spawning in Trial Chambers

[slayworldspite]

Hi,
My friends have looked for trial chambers but told me that they spawn no mobs. I checked the logs and saw this. (not everything, sometimes it shows other mobs or other attacks etc.)

I told them to look for more trial chambers and tell me if they also don't work. I tried taking out a plugin I had for keeping chunks loaded for farms and restarting the server, but it still didn't work. I did the same but this time took all plugins out, but still no mobs. I then went to one of them and saw the spawners had no mobs in them. In the F3 menu, it said it was inactive (trial_spawner_state: inactive). I then spawned a zombie egg and right clicked it, and it turned active and started spawning mobs.

My theory is that when I loaded the chunks with Chunky, something went wrong.

I've checked out this thread (spigot), but it still didn't work (except the spawner I added the zombie in)

Thanks

In case it's important here are my plugins:

KeepChunks
Chunky
Dynmap
ViaVersion
Floodgate
AutoBackup
Geyser
EssentialsX

I also once did /killall hostile but I don't think it should've killed the ones in the spawner, especially ones in unloaded chunks.
