What does this pull request do?

Closes #5741 .

Steps to test these changes

Equip 2 or more items that create a set bonus with base stats (str, hp/mp, magic skill), zone and see that the mod is applied but player doesn't have the stats

Apply this PR and see that you do get updated stats immediately after zoning
