Gridcoin wallet acting strange

This post is more of a question than anything else.

Yesterday afternoon a got a windows notification that sounded like I staked in Gridcoin. As I do not have more than ~600 GRC.
I found it quite interesting why I would stake this early, but hoped my very best.

I opened up the client, and there was nothing. So I checked my logfile and found the following:

As far as I know the client thought it staked, but somehow it disappeared. So my best guess is that it was either an error made by the client or maybe I was temporarily on a fork?

If I was on the fork, it would have been nice to see it directly in the logfile, that the client found itself on a fork and corrected itself.

Can someone please clarify for me what happened.

Cheers
