Puck and Ecobee Flair seems to get zone temps confused and roasts us?

House is a single Puck controlling a mini-split for main living room zone, + an Ecobee that controls a furnace for front bedroom zone.   Using it in "AUTO" for weeks now and its been mostly GREAT. 

Except.

It every so often seems to suddenly get super confused.  Like Flair seems to get the 2 temps mixed up.  So the front bed zone (Ecobee) will be like 2 degrees under the setpoint (67F).  Then it will try and run the LR Zone minisplit higher and higher and higher untill its 75-77F and its STILL blasting out more heat. 

The PUCK itself shows all the right data - "67 setpoint, 75 actual" but its still running that minisplit for all its worth.  Would probably get to 80 if we don't stop it. It really seems like the zone/room assignments are wrong and its trying to move the Bedroom zone temp with the LR split, but its weird the same settings / setup has been working great and nobody has changed a thing. 

Today I came home to a 75F living room and a 64F bedroom with the whole house set to 67F for the day, nobody was here, nobody was changing settings, and this same house worked perfectly fine for the last week.   Nobody changed anything at all it just seems to have "gotten itself confused".
