I moved the game to another disk, updated, and the save file is gone on both versions((0.24 and 0.25.), I got basically everything finished. I tried moving it back into the original disk and launch and nothing is found. Are there ways to retrieve?

It's possible the data is still there.

There are 2 files saved on your PC that have your save data in them. 

• Auto_Con_Save.sol
• Con_Save.sol

Using the file explorer on windows you can find the saves of all your flash games here.

• %AppData%\Macromedia\Flash Player\#SharedObjects

For example here is what the full location is on my PC.

• C:\Users\travi\AppData\Roaming\Macromedia\Flash Player\#SharedObjects

Then you need to look for where you have your game saved each PC is different so i won't know where your game is saved but for example here is what mine looks like.

• C:\Users\travi\AppData\Roaming\Macromedia\Flash Player\#SharedObjects\49V92H6L\localhost\Users\travi\Dropbox\Conquest Game\ConQuest0.24Itch.exe

If you copy and paste one or both of the .sol files into the empty folder of the new version you should be able to load your game like normal. For me I'd have to paste the files here.

• C:\Users\travi\AppData\Roaming\Macromedia\Flash Player\#SharedObjects\49V92H6L\localhost\Users\travi\Dropbox\Conquest Game\ConQuest0.25Itch.exe

good
