as far as i can tell - never had issues with resetting terrain
done a village myself in a survival game and dont seen any alterations to the terrain except for those i made (playing singleplayer on a single world)
of course i move around a lot - currently devastating a mountain for all the silver

flattend,pickaxed and modified a lot of the area
roads and pathways leading around
