I have a question. If I transfer my old saves from the previous version to the new version, will it have the updated content from the new version?
I know there's not really much added content for the free version this month (just bugs and fixes), but I ask this because the game now is 0.4.2c and my saves are from 0.4.1a, and when I play on the old saves, save, and then exit the game, the save file still says 0.4.1a, not 0.4.2c. The new progress did save, I just don't know if the save is now up to date with the game's current version. I hope this makes sense.
Saves between versions tend to work semi-well assuming it's not something like 0.3 to 0.4. However, some things tend to glitch out and work sparsely if at all. The save itself always remembers the version it's created in, but the game you open will try to be the one that the game itself is.
If you want reliability, you need a new save. If all else fails, save edits do exist, though it's incredibly difficult to find the right attributes on this game.
