I started : A Giant Battle today and I wanted to give some insight since I have had a major problem with this adventure..
I am completely stuck now since normally the leader in the larger red circle give out (Robust Tools) (Quest Getting Close complete..) so you can build the (Bridge Construction Kit) and this complete the second sub-quests.
But even after killing both side leaders using Evil_J guides or German bogini (Tuxingen) guide that attack the left side none of the camps resolved the quest and none of them provided me the Robust Tools.
I have now open a support ticket but I wanted to pass this information in case someone else has this issue.
You can see my current map progression on this image that show where the 2 leaders that should have complete the first part of the quests and both have been killed and I still have 0 Robust Tools.
Lots of wasted troops for nothing since I wanted to see if the other side would give out the Robust Tools but none of them resolved complete adventure stalling type of bug.
