Rosetta and dwarves PISSING ME OFF!

[ForeverZeroUltima]

helllllllp!!!!!!!!!!!!!!!

when i go to Water Dragon Isle to save the fairies from teh dwarves, Rosetta keeps dying on me!
the main reason i started this new game was to get one of the triple techs, the one with Serge, Leena, Razzly, and it calls for Razzly's level 7 tech. you can only get it from Rosetta IF she stays alive, but she KEEPS DYING ON ME!
1. i save Razzly
2. i DONT use Razzly to fight the Hydra.
3. the hydra dies and doesn't give birth to another one.
4. i kill the dwarves.
5 the dwarves DONT survive
6. ROSETTA DIES!!!!!!!!!!

how the heck do i prevent her from dying???????
