No, I don't use OneDrive. and Not happening everytime I working on to file the pattern and workaround of it. because not everytimes but most of the time it does reset when change the values manually. but it not happen on other setting like cheat_mode = 1 which I changed manually also.
But I think maybe come from the "developement_mode" is not the initial setting in My game setting because in the config file it doesn't have 'developement_mode = 0' like 'cheat_mode = 0' but I've to input whole command "developement_mode = 1" to the config file at the last line of document.
