pirates! crew morale?

[CB..]

ok im confused---sid's pirates ---is there any method of improving the crews morale once it's dropped--once i get the frowning morale face indicator nothing i do ever changes the morale---even after finding two buried treasures capturing two named pirates (huge amounts of gold) the daft apeths are still on the verge of mutiny stopping me to demand i divvy up the gold every few minutes --nothing seems to cheer them once theyre down--only thing i'm able to do is divide the booty and start again with fresh crew--which means i lose 6 months etc and can never get a sizable enough crew going to really cause mayhem--

i found henry morgans treasure (with the crew morale at rock bottom) 10000 pieces of gold---no difference what soever - i returned to the ship and immediately got the demand for the booty to be divvied up

surely this isn't working as it should
