Thanks to some helpful testers, you should now be able to restore missing
items from the Together event of this April. Head back to the same rooms as
had the forges and follow the new directions.
You should be able to make basically the same items as the ones you lost (the
materials won't necessarily match), or you could take this opportunity to redo
them. No orbs or scraps or whatever are needed, the restoring system is based
on things you already made so you won't need to pay for them twice.
If there are _further_ problems let me know. I won't be taking another massive
break.
