Unexplainable "pickup issue" with logistics

[mahaniok]

I have multiple units right next to the road that has plenty of logistical points. And it's very well connected to SHQ. But many units all got "black" supply with "pick-up issue - unit was not able to find a pickup point".

I am happy to upload a savegame but can't figure out how. Attaching doesn't work. Adding link to drive doesn't work. Help appreciated.

nevermind, I found a bottleneck. Still, the question about attaching the savegames is an interesting one.
