So it seems that if you're under another force and not the default one player when you rack up 6 chests, for what ever reason, it becomes player force , instead the force you are assigned to.

excellent mod though.

Thanks for reporting the issue.
I published a fix for it now, I don't know how I would test this so I trust the small change just works. If it doesn't, please let me know asap so I can look into it.

Glad you like the mod!

Oh man, it makes life so much easier, specially when used with Loaders Redux, mass storage has never been so easier for both trains and storage :D
