If the the flag.tga is in the flag folder it's correct (when unpacked).

Okay, lets try something else;

move flag.tga up to Nosophoros folder ( ~/dominions3/mods/Nosophoros)
and change the line 3175 in Nosophoros.dm from

#flag "./Nosophoros/flag/flag.tga"

to

#flag "./Nosophoros/flag.tga"

(note, there's diffrence in lower case and upper case letters).
See if it works.


another thing you can try;

switch the flag.tga out from another mod and see if it have any effect.
