Over the last couple of updates, the game getting stuck on autosave has become much more common for me. It's especially annoying because any buildings built aren't saved, but the resources used to build them are gone.
Hi Steve,
I am experiencing the same issue. Have you recieved any technical support since you posted this?
only way to be sure is do a hard back up each time you exit to the main game page .
auto save just does not save alot of times .
I've been having the same issue for months on Android although I didn't notice the resources side of things. Unfortunately if the autosave gets stuck, the save when exiting the game also gets stuck.
