Steps to reproduce:

1. Open attached project
2. Open "scenes/main"
3. Run "main" scene in unity and press "Start client"
4. Build and run project. Then, when the build loads, press "Start server"
6. Type in few symbols and press send
7. In the Unity console notice that packet was successfully received
8. Get back to server, type in more than 250 symbols and press send (this will make sent buffer longer than client can receive)
9. Notice that Receive() is being called endlessly.
10. Close server (standalone build) and notice that console is still being spammed.
