It's probably the WildBoar mod causing the loading issues. It's a little creaky around the seams and I'm still considering pulling it from the Workshop.
I also tried to run this mission and ran into the same loading difficulties. :-(

Paskinder Singh Yeah I had both. It might've been one of the other mods I'm running that was conflicting with it. I'll try it with just the bare minimum

Акула™ unsure what's going on there, do you have both Contact and the Ambient Boars mod? I'll try and take a look at it this week. It probably is buggy as I threw it together in an hour to cash in on the meme! Thanks for checking it out though

finally, a REALISTIC arma scenario

Hey man, for some reason your scenario won't load for me. I will get to the map, click 'Continue', then for an instant it will flash a frame of gameplay where I see a laptop, then I am back to a loading screen. The last loading screen never progresses.
