Yup, those toxins keep leaking out, I keep dowsing to see if they are new and they are not.
This has been ongoing from organs and glands...I am wondering if a sweep would help....
Maybe try replacing Toxins in your script:
label Toxins # released after killing
dwell 120
vbackfreq a 0.04978707 0 66.6 # (s^-3)
vbackfreq b 2.71828183 0 66.6 # (s^1)
sweep 558899.6665 558899.6765 .01 #
