I feel the need for a little statement as right now basically everything goes wrong here. As I already mentioned in some places I am currently reworking the whole Multiplayer to give the Host/Server more authority over the game which should finally fix inconsistencies between clients as a result from lag, packet loss, etc. I am also preparing some more improvements especially to take off some usage from the game host due to the new packet transfer.
As this takes quite some time, we have decided to release a Bugfix version which should fix the most annoying bugs, especially some compile-time issues as well as the most prominent that causes bosses not to fire at you.
However due to the update of some libraries the OS X release gives us some trouble. As soon as this is fixed however, we’ll publish the current development code – which has been tested for some time now – to public so shorten the time to the next full-blown release which will then hopefully be heaven for all fans of Multiplayer.
Sorry for the inconvenience.
