Yields not displaying on all tiles.

[SpookyDillows]

I play Civ games with yields on at all times.

I'm playing my first BERT game and noticed that entire blocks of tiles show no yields, even farms and other improved tiles in my capital. By adding and removing civilians working those tiles I can tell that this is just a display problem, but it's still a pain. It's not all tiles, but seems to occur on groups of tiles in a clump.

BTW: This is different from the problem I just posted separately about the +1 energy yield on worked algae, which was NOT a display problem.

Sorry if this has been posted elsewhere - I couldn't see it when I scanned the list.

Edit: Upon re-loading, the missing yields have come back. Not sure where they went... I guess they'll go walkabout again...

Addendum:
just to add that my now correctly upgraded algae inside the borders of an aquatic city won't allow me to build the biofuel plant. It appears dimmed in the list of build options stating that I need a worked source of algae. But that's what I've got.

The fact that it appears in the list at all suggests it knows there is algae present, but it isn't registering the fact that it's been upgraded by my worker.
