Hey, I've found out that if you are mining or herbing a node/vein and spamming mount at the same time you can use a node 10 times. Then it disappears.
A tip is to bind mount to mouse wheel up and down and spam scroll while taking a herb/ore.
I've been using this for 3 weeks without any problems. Maybe it works for duping mounts or enchants, havent tryed with enchants/mounts tbh.
I wanted to post this in elite but I dont got access to the elite forum
Good Luck
