Unable to join server slots >128 System.IndexOutOfRangeException

[barf]

Hello, the AssettoServer is throwing System.IndexOutOfRangeException when clients join slots >128 for me

To reproduce configure a free roam server with more than 128 slots, join the slots >128, the client (AC) appears to connect but hangs after loading.

After client loads the server logs the exception as shown:
