Actually it seems to be ok on your screenshot, look closer, it have straight line parallel to horizont, part of this line simply covered by shadow.

Yes you cant take bags placed in editor, but you can pick up bag you droped, there is a 2 buttons above list of items: 'ground/bag', switch to 'ground' and you should see your bag.

i can confirm that, had this glitch, but couldnt find how to reproduce it xD
