IF you are experiencing issues with Mercenaries not having stats or blank pictures/etc. I can confirm, that you have failed to install the "files for your game directory" properly. You may have inserted the files too deep into the file structure, or otherwise just not replaced files when prompted. People especially seem to miss the Ship and Object zip files.
Its all very annoying I know.
Good news!! The latest version of GC3 makes it possible to edit mercenaries and the Bazaar WITHOUT using the game's directory!!! This means the ONLY files I need to put in the game directory is a zipfile with the preview ships for the various custom fleet styles.
This means the next version of GRM will be much easier to install, and if you do make a mistake, the consequence is incredibly minor (you won't see a ship when previewing/editing the appearance of a race's ships.). This is a really great development!
I am busy creating some content to make the next version of GRM worth downloading... I've been raising/training a puppy, so I've been very distracted... I can't promise much, but at the least, you'll have new race portraits and new citizen portraits and a shiny, easier installation.
Thanks for reading!
