Better Account Synchronization
I have published about three or more packs packs but two were left unclaimed and never will be. Even though the pack was named under my username (ZachMC back from 2017 now renamed to GenecroMarX, same account) it's still technically "isn't mine" because it's not on my submissions page.
Make it so that users have an account verification system and that they can claim stuff that "aren't currently owned" by anyone.
