Bug Description
After server restart, entities that were restored have wrong bbox - it sits somewhere under the ground, as shown on screenshot. If such entity will be moved, bbox will return to proper place.
This seem to be server bug, not just client representation, as tasks (one that I develop, for instance) report "Too far away" error for such entities.

I think this is not a bbox issue, but an issue with the position of the entity. At the time when the entity is read from the database, the terrain surface has not been restored, so the Z coord is incorrectly adjusted to a default height near sea level. It is not then re-adjusted when the terrain level is restored.
This is not going to be an easy one to restore sadly.
Fix notes:
If the terrain is modified, a pass needs to be done to correct all entity position which are constrained to the terrain, but this can be done in place without propagating the change, or issuing operations/events as all clients and observers should be able to similarly correct themselves.
