For a very long time I've been making a guild base but everytime i rase ground it leaves a hole where two tiles are seperated. I use Flatten/Blur to fill it but it only saves one side or the other, it never saves the hole fixes. The same was happening with trees, where I would shrink and slide trees under ground so to sink island without having floating vegetation but it wouldnt work. after 40 ****ing tries I got it to work by using Cryects Tools to completely remove the Tree models from that ADT but even now some remain. Although the tree thing really sucks, I'm more worried about the land and the holes, my guild is depending on me
