When trying to increase width of relation views on an entity page, the entity view gets deleted. See video. Very strange.
Somehow this bug, combined with the view rules I had, have made it so there are no rules, and even as the admin I can’t create a rule. The views option is just grayed out. Unless someone has any ideas, I might just have to delete this database and start over.
This was a brand new database, so it’s not the end of the world - but if this bug happened to one my actual databases, that would be pretty devastating.
This is even stranger than I thought. The entity view was migrated to another database! But obviously it didn’t have the same field layout, it just had every field enabled.
Here is the setup. (1) Project has (many) Modules. On the Module database, I was showing “fields from related entities”. So I was showing a relation view from the connected project.
Then when I tried to make that relation view wider, the entity view disappeared from the Module database and showed up in the Project database.
