Shift-e has never worked for me, causes a crash. I have since just stopped using AAI for mining because it caused a lot of hassle with ammo loader filling miners and miners filling haulers, so all my coal/omnite was being sent out of base to the haulers, ha!
Yeah, the Shift-e gui was pretty finicky for a while. I just finished uploading 0.18.21 which follows up on overhauling the GUI code to be more in line with the API changes. It seems to be working now as far as I'm able to test it, only time will tell how it holds up to real world use.
1) if AAI car has been stopped to work (out of fuel), and it is in the range - it does not fuel it. I think I put fuel in the chest after it, so the car stopped before.
2) AAI cars with AAI vehicle fuel are tracked as no fuel, and will be shipped with coal from the chest (trash in the inventory for passing cars)
I believe that (1.) is now fixed. There was an issue where in certain cases, empty chests would hold on to their consumers instead of releasing them, causing both the chest and the entity to stop working basically. It should be resolved in 0.18.21.
As for (2.), I'm not sure if it maybe has been fixed on the AAI side of things or perhaps I'm just not doing it right, but I can't seem to replicate it with the current version of the mod. If you still see it happening, let me know and perhaps link some images if it's not too much trouble. I'll see what I can do to resolve it from my end.
Thanks to both of you for the input. Don't hesitate to let me know if you run into any more issues.
