Hi Bloody Mess, I have had what may be the same problem trying to use the PFM 3.2.1 to edit ETW mod files (I reported it
here). You wrote that you were trying to make a flag mod. For what it's worth, I recommend the
Additional Units Mod optional graphics pack which includes flags. You don't need to use the main Additional Units Mod, if you would like to just use the graphics pack.
You asked whether any PFM works for ETW and NTW. I can edit mods for ETW using PFM 1.5.3 which is a feature of husserlTW's
EasyDB resource. (If you start EasyDB, you can select PFM from the options along the top to start PFM 1.5.3.). This works for editing some existing mods, but there are two problems: (1) it crashes when attempting to edit some mods and (2) it crashes when I attempt to extract any database table (to make a mod) except unit_stats_land and unit_stats_naval.
I wonder if there is an ideal PFM to use for ETW and NTW - presumably this would be a PFM somewhere in between version 1.5.3 and 3.2.1? Since this is the Rome II Modding Forum, I'll re-post this on the ETW Modding Forum to see if ETW modders can advise on this (and to avoid going off topic on this thread).
