Yes, I doubt coops will take off (pun intended!) until the CTD issues are resolved. This was interesting from the guy who runs the ATAG server:
"Hopefully we'll get a patch out soon, so we can include some of the other missions we've made that are more focused to the formation/bomber flights/ground pounding. Just in the current situation of the game, it's not worth running until the launcher issues are sorted.."
From
here. I can't wait for these types of missions but agree there's not much point starting them until people can reliably take off, fly a decent length mission and land again without crashing. Hopefully the next patch sorts out the memory leak.
