Yes, that's the link between the loot and the MCDs. If it's 0, you get nothing. There's a tooltip for values carried over from the base game (though these items may have been removed in X-Chronicles, IDK).
There can also be certain conditions where these items are
not recovered, I recall 'allowObjectiveRecovery' and of course 'recoveryDividers' can be set too low.
If you don't want to use Quick Battle, I'm afraid extensive cross-checking of items, MCDs and terrains is the only other way. And not very precise, since to check whether an object is
actually on the map and just not
potentially on the map you kinda need to
see the map.
Personally, I'd just close my eyes, click OK in the equip screen, CTRL-K right after and wait ten seconds.
