Additionally, the updated mod conflicts with the following two, and I'm not sure which one it is
https://mods.factorio.com/mod/combat-mechanics-overhaul
https://mods.factorio.com/mod/shield-projector
Failed to load mod: Failed to close the file shield-projector/graphics/entity/shield-projector/shield/floor-southwest.png.

Sounds like you need to delete Shield Projector mod and redownload it. It is corrupt.

I'll investigate the other issue. Was it working before the latest update? I don't believe anything relating to AAI changed this version.

It can still be used before the update. AAI, I only used graphics, I also used these mods

Thank you for your answer.

The option to not overhaul belts cause the game to crash, error on splitter. After the update of angels.

This error has been occurring since the last update.

I also used Loaders Modernized as a loader with AAI Loader as graphics.

Fixed
