Hopefully that takes out the crazy pink and red sprites and you're left with a very subtle heather

Hi, in the original map theme, sprites (those little things that look like grass tufts) are not used, partly for this reason but also because they just look terrible especially because they poke through lawns and look awful. So, instead of very subtle mountain heather, you have bright pink and red sprites. This is not nice :D
It has to be a mod you are using that turns sprites on. Some mods stay active even when you disable them (I don't know why). Turn on your mods again and turn off sprites. This is an option in Theme Mixer
