I am noticing some "problems" - I have large piles of gems on the floor in my house and when I pick them up, they do not stack when I try to put them into a new bag. Also, I had a bag or two with gems in my closet, which similarly did not stack when I took the bag out and tried to stack them in the bag. I even tried to transfer to another bag first, with similar results.
Yes, I had tried to reload, but was still having the same problem after reload
Basically, you have to take possession of all of your gems/bags of gems, then reload to get it to work. You may have to do it more than once if you have lots of gems
