I did find the correct version eventually... though you still need to download the LocData fix for the correct M_carcasses.loc file. I was just curious if there was a newer (or final version) you've completed.
All in all, I love this mod. It adds a lot of flavor to the game and more interactions in a system. Though the spawn rate may be only 10% for fleets or convoys per check it's more like a 60% chance of encountering one or more in any given system.
On side note, the only other mod I'm using at the moment is changing the exp coefficient from 0.1 to 0.2 to ramp up exp gains. With the fleet mod it almost feels like I'm gaining exp too quickly.
Thanks again to the modders on this forum.
