Old thread but I'm going anyway...
Okay, i'm working on my Harbour Charts Mod and have come across some odd things like nav buoys leading you to a dead end in Stavanger:
and rules not being followed like Red Right Return where red buoys should be on your right side when returning to harbour. Basically, I want to edit the locations of buoys using ME but before I break something I just want to ask if I alter their locations and/or add more and save that file, say Total Germany, will that cause any issues? Is there something about altering the default campaign files in that way that I could screw up? Also what files have been changed by overwriting it: just the .pj file or the whole Total Germany folder?
