Rather than create several new issue reports, and then find out its PEBKAC, I'll report here, and later create if required.

First, and largest issue;
(Almost) complete system lock up after a while (less than 24hrs). Screen not updating, no response to; touch, "browser_mod" commands, or SSH. It will still produce a valid response to a ping.

2nd;
Often, after reboot (power cycle) will result in a desktop login screen, not the page in "fullpageos.txt". No keyboard attached, nor are any scripts modified. Only Hide curser applied.

3rd;
(Reported by another member of the household.) A Reload/Refresh prompt is displayed, however clicking it just results in a white screen.

Hardware: Raspberry Pi 3B
OS: FullPageOS 0.14.0 (not overclocked)
Usage: A single webpage (HA dashboard, kiosk mode).

I'm using the same config as for 12/13, and didn't have the above issues, but had others prompting me to try 14.
If you require any logs, please direct me to their location(s).

Thanks
