How do I update my scenario for Fall Patch?

I am getting a crash when building a unique great war infantry I added to my scenario. It is not the SQL, unless they added something I am not aware of. Before patch never had any issues like this and have added plenty of units before.

I am guessing it must be the patch. So, what is the best way to update it so it is compatible with new patch? Thanks for any help.

The scenario is called the WWI scenario.

Alright I figured out I did not set VFS to true. Do I have to do anything separate to update the scenario or does Modbuddy do that automatically?
