I attacked another player. It was from my moon against his moon. He was a yellow, honorable, target for me.
When the attack hit, I got a combat report, but that CR showed that neither player had any damage, no loot, no DF.
I figured it was a rare bug and I got unlucky. When my fleet returned the player was still offline, so I sent the fleet again. The exact same result happened again, where it produced a CR, but neither player had any damage, no loot, no DF.
See attachment for one of the CRs.
Any idea what this is?
