It's a memory optimisation thing, I would think. Think about how much memory
you could save if your'e emitting a lot of particles with short life spans
over a period. Could turn out to be quite a lot.

"When the playback head reached frame 10 another particle with ID 8 was
emitted"
Pretty much the same problem, baaaad particles...

Subject: Re: Particles sharing the same ID
I've seen it with Initial States
I'll try to explain:
Particle with ID 8 was emitted at frame 10
Initial state was set at frame 10 so particle ID 8 is now present at frame 1
When the playback head reached frame 10 another particle with ID 8 was
emitted
The docs say that particle IDs are unique and it's only indices that are
recycled, however that wasn't the case.
I'm afraid I can't help with emission events

Jordi, didn't you have something like this a while back, something about
particles being re-used in emission events?

I spoke to fast! Have a look at this:
'INFO : Particle_ID 0 belongs to pType 0
'INFO : Particle_ID 1 belongs to pType 0
'INFO : Particle_ID 3 belongs to pType 0
'INFO : Particle_ID 3 belongs to pType 0
'INFO : Particle_ID 5 belongs to pType 0
'INFO : Particle_ID 6 belongs to pType 0
'INFO : Particle_ID 6 belongs to pType 0
Lines in red are actually 4 different particles... not good at all !
