SH2: French sub do not work?

I've been trying a pack of a few subs in SH2 which have been tweaked to work as human, and I thought it was strange that NSSDiane and NSSRedoutable had not been touched.

I quickly set up a mission in Kriegstanz and gave my player a Redoutable... Crashed without a hint: no Janus error, nothing. NSSDiane worked though.

I've been searching old threads in these forums, but didn't find anything useful about Redoutable. Anyone has an idea on what's going on with this boat?.
