We did some coop mining today and encountered a minor "bug", not really a bug. Still noteworthy:
Trade Window bug when coop mining
While small miners are filling a Hege, the Hege can't use the trade window function with a hauler. No ore is transferred, even though both parties can use "accept".
Reason: the amount of ore in the Hege's or the hauler's cargo space changes, which seemingly upsets the trade screen.
It can be stopped easily by telling the "filling miners" to ceas mining for the duration of the exchange.
Cannon, the coop mining feature is cool!
If you add an "autodrop all" command, that one can bind to a keystroke, then the small miners would be happy too and could create "bundles of ore" in space in preparation of haulers. If you want to avoid big numbers of floating ore, just up the cargo space of the small miners a bit. It doesn't make much difference.
