Are the new/clarified missed trigger rules applicable only to Houston until the TRM is updated in January, or will they apply to Summoner Skirmishes before January as well?

Ruling: The new trigger rules are officially for Houston, with tournament rules being updated in January. However, it is up to Head Judges of individual events to decide whether to use the Houston rules or standard tournament rules before the January update.

Nuances:

• The rules were described as "hot fixed into the TR as an addendum" by one contributor, though the official article states they are for Houston with TRM updates coming in January
• Different events may have different rulings depending on Head Judge discretion until the January update
