It seems it has never been reported, so...
If you ban, demote or purge an user, the /admin panel is immediately refreshed and checkmarks appear and buttons text change (mute -> unmute, for example)
but when whitelisting/unwhitelisting, the panel is not refreshed (checkmarks remain unchanged, button text continues to show "whitelist")
If I enter the "manage permissions" page and back, panel is correctly refreshed
[1.0.0] /admin panel not refreshed when whitelisting an user
Re: [1.0.0] /admin panel not refreshed when whitelisting an user
Thanks for the report. It's now fixed for the next release.
If you want to get ahold of me I'm almost always on Discord.
