About [TIMING] start frame and end frame influence

[illuminix]

hey DarkElf, thank you for your file, i have downloaded it and tested, and it works just fine, and this was exactly what i was describing.

so i went back to my file, to narrow down what was causing my issue, also trying to simplify the scene so i can upload it as well for anybody interested.

while testing, turning things off, figured out it was the particle physics that was different.

so when i turn off the particle physics, everything works as intended, particles are all affected.  however, when i turn on the particle physics, the problem i described earlier happens.  not sure if this is a bug, or my setting is not right on the particle physics.

would really appreciate any help : )

i have uploaded 2 screenshot of my current settings, and also uploaded the max file (max 2018, vray)

thank you in advance for any help!
