Slitherine

My Slitherine installation includes this addtional data folder (the 64 one).
My Steam installation does not.
Is it safe to delete the 'Order of Battle - WW2_64_Data' folder? It looks like the units.csv inside is not the last version.
I get a bit confused as I thought the 64 pointed to the 64-bit version, but Steam surely does not install the old 32-bit by default?
I do have a 64-bit system...

Yes, one is vestigial and can be safely removed. Once you have done so, it will not reappear with new patches. Just be careful that you choose the right folder. The latest one, NOT to delete, will have the Allies campaigns, as a clue.

As I suspected. Thanks for holding my hand, Bru
