No

do you have a mod like this but for air units?

It is highly unlikely that this mod causes graphics-related crashes halfway into a game. It just makes SQL statements for the database. The worst thing that may happen is a crash at the START of a game.

Regardless we'll look into it. In the meantime try these things:

1. Does the game crash when loading autosaves of previous turns?
2. Switch the DX version in the launcher to the one you don't usually use, then load the crashing save. Does it still crash? (Personally I use DX9 because DX10/11 causes some graphical glitches)
3. Follow the steps in the Core Mod workshop page for troubleshooting (https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2309504487) , then load the crashing save. Does it still crash?

Or, was your game a game that didn't start with this mod, then you decided to install this mod on turn 110? Maybe that would cause problems...

unfortunately this is not working for me using the latest versions of Sapiens + Gaia mod on 8th Sept 2024. enabling this and trying to load an existing save I had (turn 110), it immediately crashes the game with an error box saying something like "DirectX" error. I'm also using EUI with the Sapiens compatibility patch.

This mod only works correctly as intended with Gaia's Core Mod. Does not work as intended with similar mods such as Various Mod Components (VMC) or Community Patch (a.k.a. Vox Populi).
