Be careful, updating 2 of our stores caused the settings and languages that had been changed to revert back to their initial default values.
This caused huge issues for us. especially with settings reverting.
(upgrade from 4.2.4 to 4.3.1)
At the moment i have it in as a support ticket to get cscarts response.
Better add it to the bug tracker as well to make sure it will not occur on your next upgrade.
We will re-upload existing upgrade “4.2.4 → 4.3.1”.
4.3.1. → 4.3.2 won't have this problem.
I apologize for this bug.
