If you have created an Interaction or Object XML tuning mod, it will need updating to be compatible with the June 2nd patch. Here's what has changed: The main change is that the structure of constraints tuning has changed. This is the new structure: <L n="_constraints"> <U> <L n="constraints"> <U> <E n="key">HUMAN</E> <V n="value" t="cone"> <U n="cone"> <T n="angle">15</T> <T n="max_radius">2</T> <T n="offset">0</T> </U> </V> </U> </L> </U> <U> <L n="constraints"> <U> <E n="key">HUMAN</E> <V n="value" t="facing"> <U n="facing"> <T n="inner_radius">2</T> <T n="range">10</T> </U> </V> </U> </L> </U> <U> <L n="constraints"> <U> <E n="key">HUMAN</E> <V n="value" t="posture"> <U n="posture"> <E n="body_target_tuning">INTERACTION_TARGET</E> <L n="posture_manifest_tuning"> <U> <V n="posture_type" t="enabled"> <T n="enabled">15537<!--Posture: posture_Stand--></T> </V> </U> </L> </U> </V> </U> </L> </U> </L> You should note that the way you create a notification pop up has also changed. This is the old way of doing things: <V n="text" t="single"> <T n="single">0x6922E38C<!--Buy Camping Supplies--></T> </V> And the new way: <V n="text" t="enabled"> <V n="enabled" t="single"> <T n="single">0x6922E38C<!--Buy Camping Supplies--></T> </V> </V> I'm sure that lots more has changed.
