This is one of those questions like, "Would you engage in an unnatural sexual act for a million dollars?". In theory, you can answer and fantasize, but in practice, no one will give you that million :D
By the way, this is a real problem for me as an organizer, and it was unexpected. And not just this. I would like to establish communication with Baratortch and the Creator on work-related issues that directly relate to the quality of tournament organization and the reliability of resolving controversial situations.
In general, I would suggest equating early OH break to a restart upon encounter, but there are many questions here, such as the possibility of avoiding the encounter, etc. Therefore, in the case of an OH break, load the save and continue without OH. The blue player then takes their turn at their discretion, without repeating moves.
As for the bugged interruption of turns, when there is no encounter and there cannot be (Jebus, Mini-Nost), either continue playing without OH, or load the save with OH from the previous turn; this often helps.
