Hi @Canadice
Thanks for posting all the information👍
There would be caching going on for sure, FMRTE reads the data loaded but have you used the freeze function on this player before yourself? if so I believe that is what is happening, FMRTE freezer is doing its job it is reverting the player to his 'frozen' settings you set.
my suggestion dont use the freezer if multiple users are editing a save until all the edits are finished then freeze the player
can I ask why several people are editing a save game?
cheers
