Within the last 30 hours or so, I have taken the Orion Special Operation misson atleast 7 times, failing all but the last. Of the number of failed attempts, 2 were because the Behemoth Heavy you are supposed to escort in the second part of the mission, spawned in an active hive skirmish sector.

Similarly, the Orion Command mission also failed once because the Unaligned Behemoth Heavy spawned in an active critical skirmish.

If this were something that always occurred, it would be just another part of the mission to make it hard. But it occurs randomly, when apparently the system can't/doesn't distinguish between an free roid sector and a sector with a skirmish. This can't be intended behaviour. I'm sure it happens with other missions as well, which involve NPCs spawning in roid sectors of any of the nine dynamic hive systems.

yes, had that with other missions, too
