When using the macro below, you can mount your Winged Steed however, upon clicking the macro again you can’t dismount. After doing some searching around, I’ve found that this isn’t a new bug. Other flying mounts work just fine with this macro, why is the Winged Steed different? For 1k gold, there shouldn’t be any bugs discouraging the use of this mount.
