To fix your game not loading in offline mode first try verifying your Last Epoch game files in Steam: 
 

1. Open Steam.
2. Switch to your library.
3. Right-click on Last Epoch.
4. Click Properties.
   
5. Switch to the Installed Files tab.
6. Click Verify Integrity of Game Files.

If you continue to have issues, you can try to restore a previous save file or one of your Stash or Character files may have gotten corrupted. 

Restoring a previous save file

IMPORTANT: Before doing the steps below, make sure you keep a backup of your Save folder.

1. Open Windows Explorer.
2. In the address bar, copy C:\Users\%userprofile%\AppData\LocalLow\Eleventh Hour Games\Last Epoch\Saves and press Enter.
3. Open each file that ends with .bak in Notepad and search for your character's name.
4. If you locate your character's name, right click on that file and click on Rename.
5. Delete the .bak extension.
6. Start Last Epoch (Do not select Offline Mode from Steam).
7. Once in-game choose Offline Mode and select one of your characters.

Deleting a corrupted Stash or Character file

1. Open Windows Explorer.
2. In the address bar, copy C:\Users\%userprofile%\AppData\LocalLow\Eleventh Hour Games\Last Epoch\Saves and press Enter.
3. Sort your filed by Date Modified so you see the most recent files at the top of the list.
4. Open your a Stash file (i.e. STASH_CYCLE_6_0) or Character file (i.e. 1CHARACTERSLOT_BETA_0.bak) in Notepad.
5. If you see a blank file or contents that appear something like "NUL NUL NUL NUL NUL NUL NUL NUL NUL NUL", the file is corrupted.
6. Close Notepad.
7. Select the file that is corrupt and delete it.
8. Repeat these steps for each of these files to ensure you remove any corrupted ones.
9. Start Last Epoch (Do not select Offline Mode from Steam).
