I was trying to get a suffix working and noticed that there was alot of excess output in the console when sending out a test message in chat.

I am not sure if my failed attempt at making a suffix is to blame, but as soon as I set it I was disconnected from the server. The command I gave to create the suffix was "/lp group owner meta addsuffix 100 " &c[&nAdmin&n]". Looking back im sure I was not supposed to try and end &n with a ''.

Anyways, I relogged and tried a test and the suffix was not there at all. It was at this point that I took a look at the console and saw a bunch of messages. I cleared out the suffix but the console is still outputting in abundance. I even tried logging out, restarting the server and relogging, but still the same thing.

I'm using LuckPerms-Sponge-3.2.60.jar on a spongeforge-1.12-2443-7.0.0-BETA-2498.jar server running MC version 1.12

Any help would be appreciated.

Try using a lower version of Sponge Forge as some big changes happened. I can recommend a version about a week old.

Or rather, the right version of Nucleus for your server. :)

(you're running an API 5 build but your server is API 7)
