I don't see why people are sorry about developers pulling all nighters - that is exactly what developers sign up for
. We all know some of the best coding happens at 4.a.m in the morning when you are in the zone on auto pilot 
On a side note, looks like a few new bugs in the beta build, some you already know of
1. Sim speed 0 for yourself (which you already know)
2. When you finish a multiplayer custom game, it sits at the awards screen and you can not get out of it. At first glance it seems like the interface has locked up, however it hasn't. If you are in windowed mode and press the X to close it, the interface prompts you to exit to windows. So it doesn't seem to be unresponsive, just some other interface issue.
We did manage to get a 3v2 going last night, though we had to swap hosts because the first host couldn't connect to everyone - so far it doesn't seem much different to the non-beta version and we all have ports open etc. Hopefully the next round fixes some stuff.
