[hypnotoad]

Is it possible to reproduce this issue deterministically? If yes, it would be great if instructions to reproduce would be added.

[hypnotoad]

Does this issue happen in 1.0 as well?

Just plug the USB port of the TXT to a computer and wait... Might take a few minutes

Does this issue happen in 1.0 as well?

Yes
