Can't load saved game on multiplayer.

[Antiglitcher101]

Hello,

I'm completely new to this game (which I absolutely love ) and using forums. I installed 0 a.d. directly from the site and it's been working great. I've played a bunch of games with my friend and we have a few unfinished games that I've saved to continue later. For one of these saves, I'm encountering a crash when trying to host. The saved game works fine in single-player, but fails when hosting for a multiplayer session.

• Game Version: 0 A.D. Alpha 27 (8c69b) 
• Both my friend and I are on the same version.
• We are not using any mods.
• I have other saves that work perfectly fine
• The only antivirus I have would be Windows Defender

The Problem:

When I go to Host Game -> Load Game and select my saved file, the match setup screen shows the incorrect map. The save shows Cycladic Archipelago, but the match setup screen displays Acropolis Bay.

When I click "Start Game," the loading bar reaches 90% and then the game crashes with an Assertion failed error.

From my understanding the error log points to a mismatch in grid sizes (dirtinessGrid.compare_sizes), which suggests a conflict between the saved map's data (2048x2048) and the lobby's map data (1024x1024).

Because it is a saved game, I can't change any of the values and hence cannot change the map back to normal. 

 

I have attached the full error log (Assertation failed dirtinessGrid.comp.txt, it is very very long ) and the saved game (savegame-004.0adsave)
