Linked triangle with no field

It is called null field. It wont disappear.

I am on mobile now, hard to type, later I will edit it.

Here is the explanation:

That's a server synchronization problem. It should resolve itself within a day or so. (However, because this is not actually an inconsistent state, it might not.)

Unfortunately, if it's your non-field, you won't get the AP retroactively.

The reason this is not inconsistent: imagine a portal within that triangle. The rule is that the smallest-possible triangle on each side of a link gets the field, thus the link which closed it could have created a field between its endpoints and that inner portal. Now imagine that this inner portal gets deleted or moved for some reason.
