[OPEN LOW] Wall is flickering in building mode and floating sitting nurse

Before patch that was released 11/09/2018, in the building mode, when overlapping the wall between the room, the new object to be built was not flickering; but in the patch version from 11/09, it is now. For example, if I build doctor's office close to STATS lab and share the same wall, the intersect wall is flickering so does the chair.

Second issue, when getting back from common room, the receptionist instead of walking he/she floating and moving in the seating position; it looks like seating on virtual chair and moving from common room back to receptionist area.

Hello and thanks for the report - could you, please, upload respective save game file and output_log - it will be very helpfull to us!

(Keeping open because of the flickering part, still need more info the be able to continue investigating the second issue)
