Μιssion 1 issue When I start the first mission of the campaign and getting close to the ships so that the package can be delivered from the first helicopter, it throws out without warning on the menu to start the mission starting from the beginning. It has to do with the problem of the campaign, it has to do with the issue that I am not doing something right in the instructions from my helicopter, for example, to keep the altitude or something else. anyone has dealt with it. thanks a lot
