synchronization went backwards

How is this even possible?! I uploaded 40 new products to the secondary site, and then used the “update report” on the primary site. As the result, the quantities from the secondary site (1 piece per item) were overwriting the stock quantities in the primary store!

I consider this a big, bad bug!

Not in my wildest dreams I would have expected that secondary quantities would overwrite primary quantities. Now I need to put my store in maintenance mode to avoid overselling, count those 40 products, and correct the primary inventory.

Seriously, I can only warn everyone from using this plugin.
