Could you explain in detail what this correction means.
If you have expansion in the expected, then it will disappear? or you have reversed the error that when it stands in the expected and there is a conflict status, then the expansion will not be lost from the expected.
If this is what I think it is, then it's already been in place for a week or so on the servers, and the patch note is just acknowledging it.
If a faction tries to expand, but all systems in range have 7 factions already, it would invade one of those systems, starting a war with one of the factions already there. If it won the war, that faction got kicked out and the expanding faction got the 7th place. If it lost the war, then the expanding faction immediately retreated again.
This is fine ... but if the expanding faction already had a war/election pending, then it would end up with two conflicts going on at once, and a bit of a mess.
This fixes that, so that if it already has a conflict pending, it won't do that expansion (it goes to Investment instead, by the looks of things).
Expansions into systems with fewer than 7 factions (i.e. almost all of them) aren't affected - you can still get those when a conflict is Pending.
...
I do wonder how this interacts with the previous change where factions wouldn't retry an expansion from a system if an Investment-powered one failed. Can you get the following sequence, where a faction only has systems with 7 factions already within Investment-expansion range?
Expand -> failed: conflict Pending -> Investment -> Expand -> failed: conflict Pending -> Investment and do not retry.
Or does it not count as "failed to find somewhere to expand to" in that sense?
(This is not hypothetical, by the way: I can think of one Colonia faction in exactly this position at the moment which has already gone through the Expand -> failed -> Investment steps of this process, and does not have any non-invasion expansions open to it at any plausible range ... but might later if some of the remaining CEI winners claim their systems. No idea if they'd be bothered by not being able to expand again or not, though...)
