Sorry, wasn’t able to get more specific info at the time. I’m using the latest experimental on a fresh install. I also tested this both with and without the mod, and it worked fine in vanilla.

Here’s the first error that appears when I select the turret I want to install.

Then the turret name changes to this.
The mounted .22 dual turret, mounted .45 dual turret, mounted 9mm dual turret, dual nail turret, mounted .22 quad turret, mounted .45 quad turret, mounted 9mm quad turret, quad nail turret, mounted MG, mounted MG turret, mounted energy turret, and mounted laser are affected; I seem to remember that all of them were affected in a previous version, though.
