Is there a limit to the number of custom particles present?

I used the FSM from the EFPSE wiki as a reference to create decorations that generate Environment Particles. The decoration name is "Env" and the custom particle name is "Custom0.png". The code works fine and continues to scatter particles over an area of roughly 5*5*5.

FSM:

image Env 0 3
image particles 0 0
state IDLE NONE 0
frame 0 0.025 0 0 0 NONE
frame 0 0.025 0 0 0 SETVAR p1 RANDOM(-200,200)

(What a terrible repetition)

So far there is no problem with this decoration, but If you place an unusual number of these decorations in the same room, the more you place, the shorter the particle's life time will be (it will disappear quickly). I am thinking that there is a cap on the number of custom particles on the map, so particles that have exceeded the cap may be disappearing. Or my knowledge of FSM sucks.
