When throwing grenades that produce a particle field (smoke, gas, fire), the first ones usually work fine but if I throw too many (maybe 4 or 5), some of them don't spawn all particles (or none at all) and I get messages like `Could not spawn particle: 'smokefield'` in console. This means I am reduced to guessing where the grenade ended up exactly and have to remember those places.

Not sure if related but sometimes when this happens, the smoke grenade doesn't even produce any sound effect so it looks like it just disappears after throwing but although not visible, the smoke field exists gameplay-wise (when I walk a soldier into it, the health bar starts getting gray in 2.6 and aliens don't seem to see me).

I don't think it's map specific (or at least it affects many maps), definitely easily reproducible on wilderness.

Reproducible with both 2.5 and latest git on Kubuntu 18.04 64bit.
