I dont tend to miss too many. The important ones get announced in the messages at the beginning of the turn. And no purchases need renewed.
Also, it is only one menu to check. Not like dom3. When you open the recruit menu then all of your recruitable location are icon'd across the top. You can click on any of them then purchase the unit, then click another location and purchase something else. The only way you can miss one is if its not one of the announced ones (rarely) and you dont open the recruiting menu at all that turn (more often). I dont think I miss many.
I am more plagued with messages of specials being offered that I cannot afford.
