Bug - when you select resource overlays on, and 'rollover' the marble overlay, it merely displays the hammer increase (+1) but does not also display the commerce increase (+2), as mentioned in the civilopedia. This is the only overlay/civilopedia conflict that I've seen so far.

Can you show a screenshot where the information is missing from your expectation?
Is this something that happens all the time with this commerce overlay, or sporadic? If sporadic, is it random or always on the same tile?

This would be information of use to the developers trying to recreate the problem and solve it.
