after loading the components I get this error message:
Extension Id for Order_of_Battle--Japanese_Army_1944-45.vmdx (oobIJA37) conflicts with previously loaded extension C:\Vassal\Panzer Grenadier\Core_Data--Panzer_Grenadier_Über_Base_Module_ext\Order_of_Battle--Japanese_Army_1937-43.vmdx
How do I correct the conflict
The quickest fix is to disable the 1937-43 OOB. The more permanent fix is to correct the extension properties. I've done that and uploaded a correct version.
Let me know if there is anything else like that. Those little mistakes pop up.
