2. The use of additional programs that speed up the game process is permitted, in particular:
- A mod to improve the functionality of the interface - HoMM3 HD,
The player using these programs and files bears full responsibility for any bugs that arise from their use.

It is necessary to either thoroughly explain why this rule is inapplicable to the situation in question (by the way, why?), or explicitly state that there is a flaw in the rules, submit a proposal to amend them, and characterize the decision as one made retroactively "due to special circumstances" (by the way, what circumstances? Does Hell instantly lose if it doesn't move the horse?).
Let's reason further... suppose for some reason we dismiss the above, but since nowhere in the rules does it indicate how to act in such situations, the episode in question should be considered a gray area in the regulations. Therefore, the AC's decision should be treated as a legal precedent that players and judges will use as a guideline, which will be referenced in discussions, etc.
Right now, there's a blitz Jebus Cross going on, where almost every turn is being finished in the last seconds. And I'm curious - does the AC really want to be flooded with complaints like "my computer lagged in time trouble, I think it's a bug of the HD mod, please allow me to finish my turn"? The question is rhetorical, no need to answer.
