Temple of Mars

[Blooo]

For some reason my Mars temples aren't giving experience bonuses. It says in the building description that it should give +1 or +2 etc, but units trained in that city don't get the boosts. Where should I look to see what the problem is? export_descr_buildings right? I've found the temple_of_battle part, and "recruits_morale_bonus bonus 1 requires factions { seleucid, }" looks like it should be the lines for Rome, but they're just not working. Works fine for other nations.

Any ideas?
