My Roblox sponsor died out after 2 hours

At exactly 12:00AM I started a sponsor of 10K robux for 2 days, at the start, it had about 3 servers and got a lot of concurrent players. But sadly, after about 2 hours, the player count died and there was an average of about 1 or even no players playing it at the time, I don’t know if it’s gonna pop back up but I’m a little scared that my ad failed.

Here is the game -

You have to keep putting robux into the game to see an improvement in CCU.
