Steps to Reproduce

In a WashingtonDC instance, inspect the script in the "Update last used date" business rule /sys_script.do?sys_id=89f27f2e7795b11087d92531df5a99dc

Actual behaviour: "Update last used date" business rule runs After, then does a current.update()

(function executeRule(current, previous /*null when async*/) {

current.cmn_last_used = new GlideDateTime(); current.update();

})(current, previous);

Expected behaviour: run Before, so there is no need for a .update() because you are already in one.
