Issues not pointing to Titles in Comics Space?

Summary: DEATHLY CRITICAL: something is very, very wrong. Everything looks fine when I am doing the data entry, but it appears broken when the Space reloads!!! Worse, the older Issues look fine -- it's just the new stuff that's broken. And the brokenness is that these Issues have links to their Titles, but those links have illegal OIDs. All of which suggests that the OIDs are being saved wrong, which is about as bad as bad gets. This needs to be investigated and fixed immediately.

For example, look at Against Blackshard 3D, which isn't showing any Issues, even though I input an Issue for it earlier today. Or look at this issue, which shows the Title as a Bad Link "x3c5y" -- apparently truncated at both the beginning and end of the string OID! How the bloody heck can this happen?

The frightening highest likelihood is that the issue is in the storage level: that somehow, the OID is getting truncated when it is being stored. (It looks like it is at storage time because older Issues look okay; it's just the newest ones that are broken.)

Note that Issue Title is a Set of Things, which is a bit unusual. Is the problem specific to that situation?
