GGG intoroduced chance for additional Scarabs to drop from Safehosue stashes in 3.9, but Vagan still could only drop one Legion Scarab at a time. I am worried situation might repeat with Asling and her Metamorph Scarabs.
This was my fault and I feel bad about it. I've fixed this now -- expect to see the fix go live when Delirium releases, sorry!
