That’s why I insist that players should first contact the tournament judges. And let them figure out whether it’s a “bug” or “possibly a bug.”
A much more reasonable approach is to have “rules that are simple, clear, and have only one interpretation.” Within this framework, a solution can be found by stating that “lag is the player’s problem.” Yes, in some cases, this may unfairly disadvantage someone, but the simplicity and universality here more than compensate.
