The bug is definitely in the elevators. I got the speed tubes and all 4 of the CEOs in the same office got stuck somehow (different elevators). I deleted the tube, and the CEOs are now floating. I can't move or fire them. When some employees got stuck before (same game), they weren't from the same office and I could just fire em and that solved it.
Also, some parts of my building don't show up, but I can make em appear by clicking "freeze" twice. Speed apparently doesn't work either; it's going on slowest now from what I can tell.
I hired new researchers and promoted them, but they don't do anything.
