I have 8 reward brackets set up for leaderboard rewards based on rank: 1, 2, 3, 4-10, 11-50, 51-500, 501-1000 and 1001+. While setting them up on the prize tables, I started getting an "Over Limit" error. After some testing, as soon as I passed 250 I started getting the Error.
I searched in the settings under limits and couldn't find a limit set for amount of players rewarded, so I'm a bit confused at this limit I'm seeing.
