It used to be possible to select a group of engineers, que up a series of reclaim orders, and then Shift + G these orders to split out the reclaim orders over all the selected engineers - it used to work a while ago but has been broken in recent builds.
Another thing that I think still doesn't work - is to be able to take a UEF SACU Engineering drone, and have kennel drones assisted to the SACU drone - I don't think that works.
Thanks for all the awesome work and continually improving the game. it's hugely appreciated!
