Lab gem xp issue

I ran a lab the other day and had the +50M XP to a gem. I threw in a new lvl 1 gem and the 50M was wasted as the gem locked to only lvl 2. I have auto level enabled and wasted the 50M XP. I haven't put in a clear no XP lvl 1 gem again due to this risk of wasted 12 min.

Every source of large amounts of gem XP except for Facetor Lenses cannot ever give more than a single level.

The same thing will happen if you use a Tora bench on a gem of low level.
