I suggest you stop using the system/save option mate, it causes all kinds of problems and is very hard to update games with it.
Luckily a very nice user we have around here AndreasR , that sometimes takes free requests, who created a save game template a while back when I requested it. It's great, gives you full control over what to save, what not to save, makes it easy to update games, etc.
I've been using it ever since and I am very happy with it!
You can download it by going here it's on page 4, the one called "CONSTRUCT 2 – SAVEGAME FUNCTION (LOCALSTORAGE)".
And if you want to make requests too you can check out his topic over here and if you get lucky/he has time maybe one day he'll do something for you too.
Hope this helps.
P.S. Of course if it's useful to you and you have the funds, I'm sure Andreas would appreciate a small donation on his site.
