Sudden bug, help

[Nat1984]

My sandbox zoo has suddenly developed an issue out of nowhere. It’s been working absolutely fine for the last few weeks, then today I suddenly started getting told that staff couldn’t find a staff room or keepers hut. The keepers are now just stood on the paths looking puzzled. Nothing has changed. They all have work zones set up with keepers huts and staff rooms that have worked fine for weeks.
I now have 26 alerts that staff can’t find a keeper hut or staff room, keepers stood on paths and animals now being neglected.

Help!

I also get these Notifications all the time

It's a bug that came with the second to last update. I have it as well. At least with the notifications. Mine do their work, though. Have you tried fireing all staff and hire new ones? Do you have work zones? Did you report to the issue tracker?
