Is anyone else experiencing this?
We're looking into this. Thanks for posting.
I'm having this as well. An "Invisible escalator & elevator" bug.
I'm experiencing this as well. Workers running from a diner on a lower floor to one on a higher floor, back and forth, through the walls. This will occur even if nobody is using the nearby elevator (both diners are touching the same elevator shaft). Unfortunately, this is more than just a distracting visual: I can confirm that while the workers are running through the walls they don't count as being in the diner and therefore aren't producing food. Though my lower diner is supposed to be staffed with 4 people, at any given time it has between 0-4.
(Nobody is the upper dinner seems to be affected by this issue, they all seem to stay put. For what it's worth, I think a few people in the lower diner used to work in the diner on the higher floor. Don't know if this is important to the support team, but I thought I'd mention it.)
