v0.64 gets closer to release date, but I'm releasing another bug fix: v0.63.3
Link back to the main post that was updated: Straitened Times v0.63.3

Normally, I would wait for the full release, but the new engine doesn't work properly and most likely I would have to return to the old one. So "stable state" mechanic was added. It saves only the state of the game - no engine variables, no rollbacks - so it's save to use between versions.

Stable state stores in your "persistent" file.

I suggest you to use "clear safe state" button after transfer to get the weight out of persistent file.

"Save/Load" screen was updated and here are examples how to use it:
Save the state of your old game while free roaming (the game wouldn't allow you to do otherwice)

Load the game with new version (same or greater)

Here is file with save screen if you want to use only Save State with your other game version (it's the same as in v0.63.3):
scrs_game_menus.rpyc
put it in your "game" folder, near "scripts.rpa"

ps. please test it, guys
