Unfortunately no, not as such. This is a common problem in large-scale (epic-type) mods with many culture- or civ-specific units + buildings which all require the same (strategic) resource — but it usually only manifests if the player actually tries to consult the entry for that resource in the Civiliopedia. Because the 'Pedia-pages are generated dynamically, based on the .biq settings, when the player opens one of the resource-entries, the game can't display all the dependencies on the Civilopedia screen, and the error-box pops up. The only way this problem can be properly resolved is therefore by adjusting the .biq. This would be up to @unartis to implement: (1) For units + buildings which only require one or two (oversubscribed) resource(s), that dependency(s) should be specified as the second (and third) of the 3 'Requires resource' slots. As I understand it, by setting the top slot to 'None', the hyperlink(s) from the resource(s) to the unit/building (and vice versa?) is/are then not generated in the 'Pedia. The downside is of course that it may not be immediately obvious that a unit/building requires a resource, therefore requiring that the information be included in the description-text of the unit/building's Pedia-entry. Every. Single. One. @Civinator has done this in his epic CCM mod. (2) In addition to (1) it may also be helpful to modify the resource icons (.pcx files), to remind the player "Don't click!". IIRC, @AnthonyBoscia (also) did this in his WorldWide Mod.
