The changes you've made to the Deer Valley Mall are out-of-date.

This building outline is incorrect: https://www.openstreetmap.org/way/335988865 
You've enveloped an entirely separate Co-op grocery store, having changed it from building=yes to building:part=yes. (https://www.openstreetmap.org/way/335988864/) 
This interior corridor linking the Co-op to the mall building is entirely fictitious: https://www.openstreetmap.org/way/1279199180 
This Co-op store used to be connected to the mall building, but was separated TWELVE YEARS AGO.
This footpath around the back is fictitious: https://www.openstreetmap.org/way/1279199162 
This Walmart was closed, it doesn't exist anymore: https://www.openstreetmap.org/way/1279199155

In Sunalta, you've added this park: https://www.openstreetmap.org/way/1279199120 There's ALREADY a park there, you added a park perfectly coincident over top of it.


*sigh*...
