Thanks for the replies, I completely forgot that engis don't reclaim if the storage is already full. My bad.

Ok, so I select targets with shift as usual and then just press G (with shift still pressed) by the end, now it's working. Thanks.

Practice zooming in and out to go to different locations. I haven’t use any other method of panning in over a decade of playing this game. When you get used to doing that you’ll never want anything different, it’s far, far superior with no downsides.
