Can multiple Skirmish byes be accumulated and used at later Regional events, and do they expire?

Ruling: Players can accumulate multiple byes across Summoner Skirmish events, but they are only able to utilize one bye per Regional Qualifier event. Byes do not expire or get automatically used if you don't attend an event.

Nuances:

• Only one bye can be used per Regional event, even if you have multiple accumulated
• Byes are not consumed if you don't attend a Regional event
• Byes persist across multiple Regional events until used
