Event variable invalidated after auto-reload

[BNH440]

The old event variable used to show some information on the team pages about a team's ranking is invalidated when the parent page auto-reloads. This is desired behavior except it results in a "team not found" error when you reload the team page without going back and loading the page over again. The team page should be able to gather its own event data in the background and then use it when it loads so this issue doesn't occur. This would also allow for auto-reloading of a team's rank and other stats which was not possible before.
