For the upcoming My Colony v0.86.0, I have completely rewritten the code that saves game files. For Regions, the change is particularly large because you no longer need to
Return to Region in order to save your region data/resources/tech. This should help with issues people have on Regions where their resources and tech are not saving correctly between the region and the subcity.
Since this is such a significant change to a core part of the game though, I am going to let the new code run on the
web version of My Colony for a few days before pushing the update out to all platforms.
If you are brave enough and willing to help test out the new saving code, please do so on the web version of My Colony v0.86.0. Test with both regions and non regions, creative, custom maps, etc. Let me know in this thread what issues you run into. This is one of the core parts of the game, so it has to be golden before the update can appear on other platforms!
