Not sure if this is the right thread or not but I have noticed something with Launcher crashes. I am lucky in that I have rarely gotten them since original release and I have only gotten them in two situations since the latest official patch.
I am currently flying the Eagle Day LW campaign (downloadable from the missions section on this site). In mission 4 and 11, I got constant crashes each time I tried to fly them or I got the plane stuck in an invisible spider web thing where my plane just hangs in midair. In both missions I had to eventually just forget about trying to play them and move on to the next mission in the campaign.
I don't get any other crash issues in any of the other downloaded single/campaign missions (so far) or QMB missions.
Perhaps someone who understands what is in the mission files (I have no idea about that sort of thing unfortunately) might be able to see something common to those two missions which are not in the rest (eg a ground object/use of weather ... or something like that)? ... perhaps it might give some indication of at least one cause of crashes?
Perhaps the Devs could have a look at some stage.
Just an idea.
