I guess I ran on the same issue but just changed the extention manually to .xcs before importing on PC.Ok, so here is my issue. I play on both PC (download version) and android (the online version). I export my save file .xcs on the PC and transfer it to my android. Then import the file and continue to play. The problem is when I play on my android and try to export the save file, it is saved as a .txt file and can't be imported. Any ideas?
