Hardware Live area refresh drops SD2Vita SD memorycard

[drguild]

Don't know if anyone else has experienced this.

Was having a few late nights playing Dragon Quest Builders and about 5:40am my system decided to do a refresh of the live area while I was playing.
After the refresh the game was saying no memory card inserted and showed no save games, but was still playing fine still despite saving just before the refresh.
This happened 2 nights in a row at the same time as I was having a few late nights playing as mentioned.
Closing the game and reopening it everything was fine again and could load and save fine, didn't need to reboot.

Anyone know what this could be, a bug with the SD2Vita system?

Here are screenshots.
