Crusade 3.8. The Tutorial scenario. Most DLCs installed. I'm not trying to demonstrate a bug; I'm asking for confirmation of the rule. If it's suppose to provide a bonus and didn't then that's a bug, not a point of controversy.
FWIW, in the MW campaign it works as expected. MW, however, doesn't use Crusade, AFAICT. E.g. no Helios Ore; no Extractors.
BTW, under Crusade the MW campaign is messed up in other ways. See the 3.7 Bug List [sic] in Support.
