So i started with a supply mission. I loaded the palet on a truck, drove to the mission marker, droped of the thing, eliminated any enemy soldire, died in the proces and walked 2km to the marker, keept it for 2min, got the info mission is done, went to pedros and requested again a supply mission and pedros told me my mission isn't finished. Did i do something wrong? I'm new to the mod so i have no clue if i missed a step but it seemd like i've done everything right...

After saving and restarting the game i could take a new mission but then again coulden't take a new one. Sleeping for 8h in game didn't work eighter.
