I like delivery missions. nice to spend a bit of time in a relaxing way and make some money in the process. But these missions are still very broken, after many years. Pickup markers under ground, at lap posts, under habs and I could go on. Delivery machines not working markers not showing up delivery to a shelf will not complete and there is several more.. It's really frustrating when you have a few multi box missions lined up and the last one fails, making your time wasted. When that happens on 3 out of 5 of the missions, it gets worse. Delivery missions are potentially great for newbros to get to know the system a bit, learn basic flying/navigation/landing, learn to cope with the "rather simple and predictable) weather effects. But the general unreliable state of these, with a frequent fail due to a single bos out of a series not completing or not able to be picked up at all is very, very frustrating and can quickly become a detractor instead of a promotor. This should be simple, basic stuff, but it seem CIG lacks the abilities to make these work reliably.
