Yup that is why an older versions save is better that way you can make progress and keep it, since the save carries into the next build. I am pretty much at every skill being 100 at level 200 but certain skills can only be upgraded with over 100,000 points now and we only get 99,999 and money is capped at 99,999,999.i shared this one a few builds ago

it will be missing the teleport and floor 20. Maybe some stuff from the jail but city roof and easy missable stuff should be there
Last time i tried a newer save on an old version it worked/loaded but the info related the newer version got lost forever in that save
