Reliable network event overflow

[BlueKillerTV1]

One of my players is complaining that every time they sell up in Paleto Bay, they encounter an error called "Reliable Network Event Overflow," and they get kicked from the server. We just can't understand why this is happening. Is there something you could check on this?

When you sell between 700 and over 1000 then you get Reliable Network Event Overflow it makes no sense you should get it must be fixed
