Hmm, I'm stumped, it doesn't happen for me and I'm sure I included all the files this time...
Could you provide more info about when and how it happens?
I can't replicate it now. Probably it was one off random glitch.
Also where is content count index?
Added a content count to the index that tells you how many entries are therein.
Upgrade trees aren't working.
It seems like not all spaces were removed - some resources, leaders, techs and one special building have pink square at their name in index.
Bonuses: Ancient Relics, Cotton and Guinea Pigs,
Techs: Animal Husbandry, Animal Riding, Metal Casting, Bronze Working, Iron Working, Code of Laws, Siege Warfare, Civil Service, Printing Press, Divine Right, Scientific Method, Replaceable Parts, Steam Power, Military Science, Assembly Line, Astronautics, and String Analysis.
It seems like second half of tech tree almost avoided using white spaces in art definitions.
Like half of leaders have pink icons.
Only one building - special one name civic (martial law) has pink icon.
Some heroes have pink icons.
Tornado feature has pink icon.
