It turns out that when I made my mod, it was a poorly chosen patch or update to start it. Mainly because there has been so many amazing new features added since 0.98.4. I have an idea of how to update it, but I'm just asking if there is a more efficient way than copying and pasting the changes in the newest update data (mainly because I'm too lazy ) But if there isn't then I shall do the copying and pasting solution.

Erm, didn't you ask me about this? I did PM you back if I remember.

If the mod isn't a total conversion (like the WWI mod is), then make sure your all_weapons.xml and all_vehicles.xml are up to date. In any mod, make sure the soldier_animations.xml is up to date. All three of these usually involve just having your mod's things at the end of the .xml file, and just copy-and-pasting it at the end of the new .xml file (obviously not the one in the game files, the one in your own mod).

Sorry I never received the pm, you probably sent it and I'm just too clueless to have seen it. My bad . But thank you very much for the help
