Whether it's a glitch or bug, we are experiencing similar behavior. This example is a two story wall (free for reservation) next to a stairwell, with doors on each story. The door, showing marker #97, appears correctly in one user's TW file (image attached) on the 2nd story with Sill to Story 2 at 0'-0". You can review the parameters with the info box showing the selected door. After the snapshot, I did a send/receive on the two comparing users' computers.
The second user shows the same door on the 1st story instead of the 2nd. Not only that, the anchor point has been relocated from Sill to Story 2 to Sill to Story 1. The distance remained at 0'-0" as shown in the info box. Image to be attached to next post....
