Here are the default flics without the famous problem of the build list of some custom units:
http://www.civfanatics.net/uploads2/Dragoons_corrected.zip
http://www.civfanatics.net/uploads2/Janissary_corrected.zip
http://www.civfanatics.net/uploads2/Conquistador.zip
The conquistador zip includes all files: in fact I've resized all the animations, too (it was quite larger than the other mounted units: in the pic you can see that now it is the same size than cavalry now); thus I've solved the problem of "disappearing".
You can also find the Napoleonic Rifleman here in his thread (adjustment made by level)
P.S. thanks to level for the help!
