As the title suggests i was watching a replay , decided to rewind . When prompted i chose to go back exactly as many steps as the current step count and the field was emptied and then stuck there . Esc button was not working and chat could be opened . Waited for a bit just to be sure and then tried the same with other replays . I have link to video below.
Bug reproduction steps
i can only assume you can replicate it by watching a replay and rewinding exactly the number of steps as the step count.

Not sure , as going back to the first step is doable by doing step count -1 , but still i assume getting stuck is not the expected behavior .
