Tnx for report,will check

this wasn't the smoothest mission. lots of sticking ai. some intel floating out of reach. and no extraction. it was shot down...

Yes the drone was destroyed,now is ok,the tasks are checked,you can play mission again or play last mission part 9 its very similar

I think you do not understand. The task number is irrelevant. If you find the image or even the documents first, they must trigger the respective tasks, but not delete the actual task. If I find the picture, then there is not on the picture a 2 or "please do not take it!"

And besides of this: Not the weapon cache caused a problem, the drone was destroyed by itself.

Tested and seems that weapons ammo was proble,it was low health so it destroyes and activated task,now its fixed and tested ok,and every task is marked with number so you must play it in number order.Tnx

No, I can not agree with that here. The construction of your scenario here, because of the spatial proximity does not allow that the exact order is observed.
A task must remain open until it is really fulfilled. A new task can be triggered, but the focus must remain on the old, open task. Or, if you want to play with a forced path, then the other objects that trigger a new task may appear only after the respective fulfillment of the old task.
You have to check the logic of your scenario.

Will check but i think problem is that you find picture before destroying weapons,you must play mission in exact order as tasks are shown,if you do some task that its not shown can mess up the mission,thats what happened in your case.Tnx for playing

There were going some things a bit wrong with the markers and the tasks:
I had to destroy the weapon cache but I've found the picture first. At this point the task fulfilled this "find the picture" and switched the task to "destroy the drone". But after I had blowed up the weapon cache, the task was even fulfilled, but the new task now was to find the documents. The "destroy the drone" disapeared. By finding these documents, the next task should be "Find the picture"!? Of course I could not fulfill this task because I had already done it before. Besides of this the marker for the picture is misplaced (in the rock). But I remembered at the drone. But after I had have killed the first enemie of five was the task with the drone fulfilled. But I had not have destroyed the drone, but they was already destroyed at this moment.
Please check what tasks are really fulfilled and which tasks are still open independently from the sequence.
The end was ok.
Many thanks for your work.
