Playng faction found some:
1. Grand Bazaar (4L market) lost +0.5% bonus to ppl grow rate. Other market structures (L1-L3 and L5) have it.
2. Some misunderstanding with forest elephants in regional MIC (for ex. Kirtan) -
2.1. Have 2 versions with same costs and upkeep (but dif level needed I know)
2.2. Regional 'Light' version w/o missile AND Faction 'Light' version w/o missil have the same parameters, but different recruit costs. (think have to be the same)
2.3. Regional 'missile' version can be ugraded. In this case it recieve +3 bonuses BUT number of 'soldiers' cut to 24 (from 36)

Hope it helps to improve the EB
