Start by reproducing the failure in a NetPlay room with the client chat menu, using the fbneo_libretro core and the listed nightly version. Compare the behavior with version 1.21 and inspect the NetPlay chat and connection-handling entry points. Done means a client can send a message to the host without the NetPlay connection dropping.
