v0.51 is the latest release, there is no version currently after.
You must be downloading some other version, if you are missing content.
If you are trying to play a save file the best possible practice is to have version of game match.
Example;
If you have v0.48 save file,
Your best bet to have that save file to work,
Is to have a v0.48 of the game downloaded and extracted.
It was said some where on here, that on older saves its possible to mix and match save files to versions of games but only going forward. I have not tried this so I can't vouch for its validity.
A v0.47 file with a v0.49 game might work. I would not trust it to be error free though.
I would not trying to use a v0.48 or any save file with earlier versions of the game.
I would not try it with any save file lower than v0.47 with the current game.
This version of the game file name should be;
TheTwist-v0.51-Final-cracked.rar
So I would look for
V0.51 save file to get the latest content.
