Dehoisting members doesn't work with the new username system discord implemented

[TheSaltyMon]

As the title says, using the manual dehoist command does not dehoist anyone anymore as it likely has to be with the new username system discord added. If there is a fix for this it would be helpful

This is due to the new 'display name' field, that isn't provided in the current version of the underlying library that Vortex uses. This is on-hold until some Vortex internals are ready to be updated.
