As was posted earlier in this thread, it seems the issue with the CTD's during the RFB v1.4 "Museum" visit is indeed related to the RFB v1.4 NSS_
SubName.sim file (all of the American subs are effected).
I compared the RFB v1.4 .sim file to it's cousin RFB 2.0 file (with its latest Patch.....April 23, 2010). I have concluded that it is so far "off center" that the issue is "self inflected". I don't know exactly why.......but the parameters within the v1.4 .sim file are far from the stock game parameters,
and far from the later RFB 2.0 April 23, 2010 Patch files. So far "off" that the game just won't allow the American Subs to show within the Museum without a CTD. I'm not going to get into the specifics, but rest assured some of the parameters RFB v1.4 had for the subs were extremely "off base" (Engine Horsepower; Engine RPM; Gravity Center; Dive Flooding Time; etc.)....aparently so off base, the game would crash.
Applying the April 23, 2010 Patch files to RFB v1.4 seems to remedy the situation. As of this date 7/25/2015, a corrected "
OTC for RFB v1.4" has been uploaded to MediaFire that will correct the issue. It adds the RFB 2.0 Patch .sim files to RFB v1.4 with no problem to game play. The link has also been added to the
Optical Targeting Correction thread.
