Intermediate table from list field disappearing (on poe wiki)

There is a strange issue on the pathofexile wiki where for some fields, namely drop_rarieties and drop_rarieties_ids, the intermediate table has presumably disappeared. Any cargo_store including those fields will fail and as such no or only partial data might be filled on a page.

It is assumed that the tables don't exist because the intermediate tables (i.e. items__drop_rarities_ids and items__drop_rarities) can't be queried directly with an missing table error. Strangely, however in Special:CargoTables there are still values showing for those tables.

Recreating the items table does not fix this issue. It think it has occurred after the last (cargo) update, but it is certainly new.

The issue also doesn't seem related to the name of the field (unless very specific), since I can create other tables with the same name for the field just fine. Haven't tried deleting the table entirely, as that would disrupt most of the wiki's pages.
