Thanks @Gemai and @Jimbeau that's helping a lot!

Would give you rep but it seems I did that not long ago. The Forum won't let me. :/
As for the Expansion thing: I can confirm that too, for active conflicts at least.
We had an election 2 months ago that stopped a pending expansion. It went right on cooldown when the Election started.
We were in Boom with a pending election. Then the conflict went pending and we had both states pending for 3 days.
Then the election started and we had the Boom and the Election in Recovery. I was like :O
In case you wanna use this: I noticed that Elections have a recovery time of 2 days now, blocking other conflicts entirely during that time.
So keep that in mind when trying to queue conflicts.
War seems to have no cooldown however.
