There are STRONG indications that the crash-on-mod-load-unless-you-delete-cache was a bug in V31 (Thunderbrd's build looks like it was broken for reasons unknown). That version of the DLL (and ONLY that one so far as I can tell) generates an incorrect cache format that it can load, but which later versions cannot. If you clear your cache, apply the patch DLL and continue, then you should be fine. If anyone gets the on-mod-load crash with the patch or later DLL, AFTER clearing any cache that was created when they were running V31 base release (5771) please let me know.
The problem with the whale missions disappearing can also be fixed by deleting the cache. I am about to update from the SVN (and delete the cache) lets see if this fixes the story teller missions.
