The new Sanctum of Masters (7/16 update) gives much more points compared to previous (if old Sanctum was around 30,000 points, new Sanctum points system is around 100,000 points upon completion)
The server came back up at 9:00pm PST, and this new Sanctum points system affected the rankings for the season ending at 10:00pm PST.
Some players figured this out and completed the new Sanctum immediately after the patch before the ranking rewards were given out, and they were immediately boosted up in rankings.
Players that didn't know about this (or were away) and didn't complete Sanctum within that 1-hour window lost their ranks to players that completed the new Sanctum.
Players have spent countless hours in earning their rankings throughout the season, only to have their efforts undone in the span of 10 minutes with the new Sanctum.
This updated points system should NOT have affected rankings for a season that was 1 hour away from giving out the season rewards.
for some reason i can't even make a ticket about it online in support section. please look into this and fix the ranking system
wasn’t an issue before the time change
