Made an hour or so progress last night and put the Vita on standby. Came back ten minutes later and it said the "memory card has been removed" lie, so lost that hour. Maybe my fault for not saving before but then again not my fault for the Vita not being able to function properly. So had to replay that and of course saved it.
Turned it on this morning and loaded up my save. Just made a good 45 minutes progress and went to save but my save files were gone and when I tried to save in a blank one, "Save failed."
Vita restarted, just tried to load it up and the entire save file is "corrupt", so that's 14 hours I've completely lost, because of the Vita.
Almost laughing at how ridiculous it is.
