@Purban said in Unable to save the game in offline mode:

To fix this, you need to find "/gamedata/lua.nx2". Create backup for safety and rename the file to "lua.zip", find and extract file "userInit.lua". Inside, find this line (should be near the top) "doscript '/lua/ui/globals/InternalSaveGame.lua'". Delete it or comment out, save the file and put back into lua.zip. Then rename it back to "lua.nx2". After doing this, saving and loading started to work again for me.

This does appear to have fixed the issue. Though it's worth being aware that this undoes the fix that caused the bug in the first place, and risks allowing code execution by exploting an overflow issue in the way the game handles save names.
Make sure you're using trusted mods if using this fix.

Jumping in on this as well rather than making a new thread. Tried everything, even breaking out the old disc copy of the game. Seems like the current FAF build doesn't know where to look for the save data folders. I could be wrong and it's a bigger issue than that, or might have simply been overlooked in the last few releases.

Would really appreciate a fix or even a workaround being looked into, nothing more frustrating than getting an hour into an offline game and having to scrap it completely because something else popped up.
