I use RPGItems and LuckPerms together

Sometimes after the RPGItems' item is used, the command bound to it won't work and player will see he has no permission

Most of time it works, but some time not

LuckPerms 4.0.11
I think the fix for #528 is included in my version

Try again with the latest build from Jenkins.

OK I will give feedback in a few days

Feel free to reopen this issue when you have feedback. :)
