How do you fix bugs on a map?

[Raigoura]

I have a map that I am currently working on and there is some problems for it.
Some noticeable annoying bugs and some particle errors.

Like for example, the rifleman's particle shot on a target unit shows white dots! Instead of the usual sparks. Also the some magic particles are colored square dots!

How I do fix those? I tried and it is still the same.

That sounds more like a graphics problem of some sort.
Does this occur on only one particular map?
If so, have you imported any edited models or the like?

I imported some many custom icons and models. Which make the custom units that I made looked nice and satisfied. There is only some bugs on custom hero's abilities, like it doesn't always work and particle glitches.

The map file is about 6.7 MB.

you might want to check the custom models animations, maybe there is an alternative attack animation which looks crappy ?
And you know that your map has to be below 4 megabytes to be played in battle.net ?
