Is it possible for a Tentacle to change itself from line to mic in any circumstance?

Before shooting I checked both my tentacles were on line level and had accurate code. I then checked the Alexa Mini and the Sound Devices to make sure they both were receiving accurate code.

We’ve gotten back into the studio after shooting all day and discovered that one of the units is now set to mic and that some of the footage towards the latter half of the day is a few frames out.

So, I checked the timecode myself and know that I set them correctly. I then re-checked that both devices were receiving it accurately yet sometime during the day the Tentacle switched to mic and no longer sent accurate TC? Is what I’m suggested possible or has happened in any other circumstance?

This is the first time I’ve encountered this issue.
