player_connect and player_disconnect are not called

[GitSparTV]

Tested by sn_changedisconnect.lua and sn_clientconnect.lua. Hooks are not being called. However player_spawn is called for example.

Also an attempt to changelevel hangs the server on shutting down

Also client hangs on loading with "Downloaded x of y Lua files"

In server console:
