I have mensioned this before, but wish to bring it up again because the problems still exist in v1.6:

-the map.rwm file fails to generate when I add a new building. I only left "core_buildings", "defenses", "port_buildings", "hinterland_mines" and "hinterland_roads" in. This works, but when I add a completly new building the rwm file fails to generate. This is weird because the game parses EDB at startup and finds no error. I didn't have this problem in v1.2

-I still haven't managed to port my new battlemap building models to BI. The items.db file format has changed in BI (maybe Vercingetorix can take a look at that ?) but the BI exe also runs fine when using the items.db file from RTW vanilla.

I doubt any other modders have a solution to these problems, but perhaps a CA members can give me some more information *crosses fingers*
