I haven’t tested this enough to be certain yet, but I happen to have lost my Internet connection a few times today (phone & hotspot issues) while using Thunder. Once the connection was fixed & I reloaded, it seems like the load failure caused Thunder to reset some settings to default such as my preferred sort order, and nav bar visibility.

I’d normally test more before posting to be sure, but it’s way past my bedtime & I’ve got a full day tomorrow, so I wanted to post the possibility before I forgot.
