anytime i create flat land right next to water the black and gray bleed a little... even if i open it back up and correct this... once saved the black and gray bleed again... it's messing with SC4 mapper map rendering... whic puts a little water (or sand) in the area it bleeds... how do i fix this? tried multiple image programs... same problem...
What program do you paint with ?
Using MS paint with a 1px wide tool should certainly not bleed
