Bug with dino comfort/health

[cardsfanbj]

Already submitted bug report to dev, but wondering if anybody else has had this happen or knows of a fix.
Loaded into my sandbox save and getting multiple herbivores with low health due to unmet needs. Haven't had it happen to my carnivores, lagoon, or aviary. Seems exclusive to herbivores.
Everything says 0 despite having been fine prior to exiting last time, and others of the same species being fine.
Trying to add more foliage does nothing, and have no highlighted territory when you select the comfort menu.
Dinosaurs
I've got a decent sized park in this save, so I can't check every single dinosaur, but it keeps happening and I get new low health or disease from unmet needs warnings popping up.

Relevant sandbox settings are:
Disease level: normal disease
Injuries: off
Don't starve: off
Don't dehydrate: off
Lifespan: normal
Status checks: off
Comfort: on

Started a new Biosyn Sanctuary sandbox and it's happening again.
Similar settings if not identical, except maybe for choosing a flattened map, which I don't remember if I selected or not on the San Diego one
Had a nodosaurus suddenly drop in health, starving, so I zoomed in on it and it looked like it was running in place. Then one right next to it did the exact same thing. Tranquilized them both and moved them over slightly and they ran off to find food.
Saved my game and closed out and just came back (about 3 hours later) and it doesn't seem to be happening again, yet.

Frontier responded to my bug report, it's a known issue. No fix at this time.
