@VVH – The only way to transfer currently is to load up the Save/Load mod, save your file, repeat the process in the online/offline version you want to transfer to, then Load that file you saved:

@madpatter – I would suggest using the same method as above, although it sounds like the Mac version might be bugged for you if it’s not saving. It should be creating a new folder called “save” for you.
