Game won't save

Not as far as I know.  I can load my save from yesterday and save it again.  Did you get a Windows 10 update?  Do you still have authority to modify other files in the My Games/GC3 folder?

I've stopped modding only using the vanilla. Hey how do I submit this for actual help.

"What we have here is a failure to communicate".

What I meant was, can you save ANY file into your My Games\GalCiv3 folder?  I've heard of a few people who lost their user permissions to write into the documents folders after the last big update to Windows 10.  It might very well not have anything to do with what you're experiencing, but it's the only thing I can think of at the moment.

I can save a text document to the save folder. from file explorer. AI can also make folderrs in my mod, and save folders in file explorer. Well I looked is galactic civilizations not compatible with windows10. It wasn'ton the list.

Sorry, I have no further advice for you.  I am running GC3 on Windows 10 with the anniversary update, and have no problems saving games.  I hope you can find a solution for your problem.

Outtakes a really long time for the load screen to come up. Something changed. Well I forgot fixed thanks. Now it takes a really time to load the save, or load screen.
