Rollback during beastcrafting rolls back items but not beasts

I have experienced this multiple times this league and it is really frustrating.

When you are beastcrafting and an instance/server crash happens which results in a rollback, the items you crafted get rolled back but the beasts you used to do said crafts are not.

I had just split a full inventory of maps, instance crashed, now my maps are back to being unsplit but I'm missing 30 split beasts and 90 yellows. This is just sad.

Hope it gets fixed someday.
