Can you upload a copy of your save somewhere please?
Thanks

So for some reason newly built turrets don't cause the error. I saved next to an old and a newly built turret, one will crash the game for me, the other doesn't.

There's the save: https://www.dropbox.com/s/w0lnxxakn365q7c/KenAAIraSEtorio_011.zip?dl=0

Thanks, will look into it when I have some time. For now what might fix that issue is uninstall and reinstall the mod, this should reset the mod's data and fix the old turrets.

For some reason the migration logic had a really obvious typo in it, so wasn't working properly. This should be fixed now just by updating to the latest version
Thanks
