Can you please use something like https://play.google.com/store/apps/details?id=com.winzip.android&hl=en to zip the save and then attach it at support.baldursgate.com - you can do it from mobile as well.
We would appreciate it grealy as our QA tried to repro but it worked as expected for them on iOS and Android with a clean save.
That's....an interesting problem, actually.... could the browser load the page? Yeah, shouldn't be a problem.... where the problem comes in is that the phones aren't really "friendly" when it comes to trying to do file management on them... There's Winzip for Android... I assume the iPhone has similar...
To test the idea, make a page with a single image, and then put them onto your device (e-mailed as attachments, if need be). That'll be your proof of concept...
