[FLASH-USERS] DRIVER_ABORT: [Hydro]: Computed dt is not positive! Aborting! Magnetized problem

I know the "dt is not positive" problem is a pretty common problem when
running a Magnetized problem in FLASH. My specific problem shows a large
increase in mass in the last two timesteps from 1-e9 to 1e30. Why might
this occur, what can I do to fix my problem?



My *.dat is attached and edited the last few lines to fit here:
