Addressed a few issues:
-If the host leaves the lobby it now makes everyone else leave and closes the lobby as intended (Steam networking defaults to migrating the host automatically instead when the host leaves).
-Fixed a crash when joining a server as a client due to trying to use values from an empty array
-Player slot count is now decremented properly when the host changes vacates their slot (since this then is toggled to a CPU slot, which, like a closed slot, doesn't count as a slot for humans).
