Using Authme 5.6.0 Snapshot and i enabled applyBlindEffect and turns out this is very buggy, sometimes will have effect, sometimes not.

I am also using AuthMe Reloaded SNAPSHOT 5.6.0 and I can confirm that the applyBlindEffect option is very buggy, I would like this to be fixed.

I can confirm that blindness is not working on newer paper builds. I guess it has to do with its async login implementation. An alternative i'm using is to set up an OnJoin command inside Commands.yml that gives the blindness effect with a 1 tick delay.
