I have same issue when server broadcast a schema object to all clients

[Not working]

_room.OnMessage<Player>("customType", player =>
{
	OnPositionChanged?.Invoke(player.id, player);
});

Working

_room.OnMessage<Player>(player =>
{
	OnPositionChanged?.Invoke(player.id, player);
});

I also have this issue but I'm unsure where it's happening. It only happens in one project under NDA I can't share. I've taken everything out, put it into another project, and no errors.

Working in 2020.1.7f1 but not in 2021.3.16f1. Using Colyseus 0.14.7.

I haven't changed almost anything in the example, I've just removed some features. Stepping through the room initialization process, it happens twice in the two frames of updating the username, and never again.

Hi there, I'm closing old issues here. Version 0.16 have been released recently. The ability to send Schema objects from server to client have been removed on this version.

Feel free to continue the discussion if you think this is still an issue. Cheers!
