I'll try to find a working mesa version to start the bisection, but as this is
a new computer build, I have never actually had a working version with it.
Might be a couple of days before I have the time.

I have also attached a savegame. Now with quicksave feature enabled, it's right
at the explosion stage. Just light the fuse with lighter from inventory.
