I dont see my old saves from game , i mean grim dawn ashes of malmouth . i tryed many thinghs to get my characters be visible in game after instaling forgotten gods

Go to you save folder (path looks like) C:\Users\YOURUSERNAMEHERE\Documents\My Games\Grim Dawn\Save\main

and check folders for characters. I think old characters have __ before their names, delete one "_".
If it doesn't work, backup them and share somewhere like dropbox.

Idid what u wrote here and this didnt work for me , also i cant play new character becouse his lvl is rolled back till 7th lvl always when i end game:(

Check your antivirus, possibly it blocks GD from writing into my documents folder.
upload your saves somewhere and post a link, I have a program which fixes them.

i turned off antivirus and tryed again , same problem this is not antivir . I thint this is not problem with my saves .

There are 3 common problems with losing progress - grim dawn doesn't have writing rights into the folder, some pricky antiviruses like to cut them (could be windows defender), cloud saves, where cloud save data overwrites new progress back - I hear it happens most often when you have both steam and gog versions.

To make your old saves appear in expansion is an absolutely different issue which I can do if you upload them.

I understoo d You but if i dont figure why i couldnt lvlup higher than 7th lvl then its useless. I got only Gog version of grim dawn . When i played ashes of malmouth there were no problems with saves and other things like polish language optimizing volume in game and lvl up characters.
