This crash appears to be strictly game related because I've duplicated it 10 times now:

EVERY TIME I KILL THE JUNGLE LILY IN THE BOOGRE SCENARIO THE GAME FREEZES!

Has anyone else had this problem?

Also, does anyone know if I NEED to kill the jungle lily? If so, I'm screwed!

ARG!!!!!!

Dear Dear Black Fiend, Please tell me what you did to correct this "showstopper". . . I am having the same problem and can't see where anyone helped you or if you overcame it by yourself. I noticed you haven't posted for awhile, I'm hoping you haven't given up. Looking forward to hearing from you soon. God speed!

A possible workaround; draw the lilies out, and then retreat into the main part of the boogre cave.. then, after they follow you, run like the wind past them back to where they were. you should have a minute or two to do your business before they track you down again. I led one into those annoying damage rooms; it was funny to hear the lily getting damaged repeatedly

You do need to get past them. I killed them from long range with burning haze and had no problems.
