How many flashpoints are there, and how are they gated

I'm playing battletech anew, because of the recent expansion.

Playing it from scratch, I saw that flashpoints are occurring right away.
And I'm a bit worried that this means I won't actually be able to complete flashpoints.

As such, do the flashpoints come back if not completed?
How many flashpoints are there in total?


Solution 1:

The flashpoints will spawn again. There are 18 flashpoints, 13 general ones, which breaks down as roughly two per major faction, then there is one flashpoint that is opened up once you ally, again one per major faction.
