After enabling the -show_err extension i am receiving the following error on exiting RTW. The game plays without a hitch.

Script error in data/export_descr_buildings.txt at line 3309, column 81. Expected faction or culture type, or 'all' - terminate list with comma, enclose list in {}
I think is to do with modding the temples so that temple of mars is available for all Roman factions. Line 3309 is:

}
building temple_of_violence
{
levels temple_of_violence_shrine temple_of_violence_temple temple_of_violence_large_temple temple_of_violence_awesome_temple temple_of_violence_pantheon
{
-3309-> temple_of_violence_shrine requires factions { germans, pontus, macedon, romans, }
{
capability
{
happiness_bonus bonus 1
}
construction 1
cost 400
settlement_min town
upgrades
{
temple_of_violence_temple
}
It looks to me as if it already is ended with a comma and enclosed in {}. I have unfortunately binned my original of this file as it seemed to be working ok. Any advice on how to correct this error would be much appreciated.
