The mission seems very buggy. In some places models are placed without any coherence, such as a door in the middle of the room and other random jumble.

When the mission is started there is no sort of "entry" or brief introduction, such as entering the party. Rather the Spy is placed behind a drawer an armchair, completely unable to get out from there. And the Wrench agent starts in the bathroom with two already chatty fellows.

On top of that I am unable to acess the clipboard by using M, which has worked until now.

Are anybody else having these problems? Anyone aware of them?

I can also attatch photo's later if need be.

Wow can't say that I've ever seen or heard of this one before! There is supposed to be a detailed mission briefing for this mission just like any others, so if that is not happening it may be part of the problem. Wrench is supposed to start in a bathroom, and spy is supposed to start of watching the two fellows who are talking about a drunkard who they locked off downstairs. I will inform my colleague of this issue, and he can chime in on his two cents here. Sorry to hear you are having difficulties.

So thats the one running about shooting at me... But there is a mission briefing.
To everyones relief, nothing seems out of order this time I fired it up.

Thanks for the prompt response by the way.

If I may utalize this thread I have another minor question. Regarding the train yard mission (#4 I believe):
The sniper is with an individual who is very happy about his status as bullet king of the ridge, who you have to ask for a bullet after each shot in order to reload. This obviously puts a damper on the sniper's capabilities, understandably since the level is so open. But first time I played the mission I got fed up with him and simply stabbed him, figuring I could nab the delicious bullets for myself, only to find that my sniper were now completely useless.

Is this a bug or simply something you hadn't considered?

The sniper was actually originally designed as just an observer in this mission, since he would be able to just shoot everyone without any consequences. We came up with the limited ammo idea as a way to let you use the sniper to get out of a tight spot, but not be able to use him to just shoot all the train guards and rush it or take out a whole enemy patrol quickly.
The bullet king was going to die a very slow and dramatic death, resulting in him falling off the cliff, but unfortunately it was one of the things that didn't make it into the finished product.

But for the sake of trouble shooting. Back when the bug occured, there were only 1 floor not 2. Ei both agents were on the same floor, and all the guests and the gunman were there too. That both floors got compressed to one would also fit very well with the random stuff being around in nonsensical places.
