[FLASH-USERS] Bug fixes for active particles unit

[Seyit Hocuk]

Hi Chris,

After applying your patch, I still get the error as shown below when 
using active particles. This is a restart from a running simulation 
which was crashing at the same point. I was hoping that this would now 
be solved, alas.

Kind regards,
Seyit
