Thanks for the bug report. I have some issues with your mod-settings.dat, but since you said it is a game-crashing error, I assume you have not even changed any settings. I give it a look in the evening.

Still Crashed on load with following error and logs

I think that base assets mod was crashed, but I put it here since I just update the mods

So I still have no idea why this happens to you, the current version have a more excessive logging behaviour, so if you could provide me a log, I might recreate it myself. Say, do you have any mod which modifies the artillery shell? I have not forgotten you.

I think so, please check the modlist.
