I've just noticed that I made a mistake when editing the classnames of some merchants in the shipnames file for SHIII Cdr 2.7.
A couple of classnames had the 'N' from the file names added to their class names - I was not involved in campaign scripting and didn't realize this until now. For other SHIII users, this will not present a problem, but GWX users may want to make the following changes using either Wordpad or Notepad:
ECT=GenericMerchantsAndTankers to NECT=GenericMerchantsAndTankers
RC=GenericMerchantsAndTankers to NRC=GenericMerchantsAndTankers
[CVW] to [NCVW]
These entries are in the Ship names.cfg file located in the cfg folder of you SHIII Cdr directory. You should be able to find them using your word processing program's search function - the first two entries are near the top anyway.
I should also post this in the SHIII Cdr 2.7 thread in the mods section.
