This has been here for a while. This is a bug in wild where the /back command skips a place. Basically, say you /warp wild to an oak forest, then a village then a mountain top. On the mountain top you do /back and it takes you to the oak forest, not the village. I find that this is only an issue when using /warp wild instead of /random, meaning you can just use /random and its fine but for those who use /warp wild it is an issue.
