LuckPerms doesn't detect Taterzens permissions and it is impossible to use Gradle with Taterzens.
I did

git clone https://github.com/samolego/Taterzens
cd Taterzens
./gradlew

That is the output from ./gradlew

The LuckPerms thing might just be my server. If you want to have a look yourself, the IP is 145.239.252.39:25591
I gave you op level 4 just in case you do decide to join(To view the mods on the server do /mod list.

Nucleoid's maven is down, meaning that disguiselib cannot be fetched. Gegy said it will be fixed by April 20th. Meanwhile you can use jitpack.

Regarding permissions, I can take a look. Thanks for report

In case it is needed, I am using the latest build of LuckPerms.
That is the one with the Carpet /player support.

Humm, I cannot reproduce this on my local server. Permissions seem to work fine, I can change them to true/false and they update accordingly ... 🤔

Permissions aren't working with CommandSpy either. Everyone with level 1 op can see the messages without the permissions in LuckPerms.
Maybe a mod is stopping it working?
