Okay, so, I wanted to see how far away from myself I could build something, and the ground ate my hide curing rack. At least, I think that's what happened, I can't find it. I was going to plop it down by a campfire and decided to test the distance while saving running time for myself. I have not yet exited the game to see if it will return to the surface.
Thanks rat girl, I am going to add a max distance that objects can be moved away from you with the scroll wheel when holding them with the RMB. However this may not be related to your issue. It seems that the line trace to the ground made by the object you are dropping (so it can sense the ground and attach itself to it) sometimes gets blocked by objects around it. This can cause the object to end up in a nearby tree or sideways on a nearby rock. Sometimes this can cause the object to default to position 0.0,0.0 on the map if it can't find a suitable place to land. Most cases have been fixed but something is still causing problems. If you can reproduce the bug and let me know exactly how to reproduce, it will be easier to fix. Thank you.
Ah, yeah, that is an issue if you drop it below the ground. It should pop back up unless is was really far below the landscape when you dropped it. I'll figure out a way to fix it, probably an initial line trace that shoots upwards first to sense if it is below the ground or not before checking for the ground below it. Seems simple to just code "dropping" something, but it gets quite complicated based on where you drop it from and the things around it that it can collide with. Thanks again. I'll be pushing a small update soon and more frequent updates afterwards which I'll address this bug in. It is related to the bug that causes the well and firepit to freak out too :D
It was so far away I have no idea how far under it was, I could swear I could see the top of the Cureing Rack when it happened, but that's a lot taller than the cot and I assume the bottom of the object is what matters for placement.
As someone who knows nothing about coding it all sounds very complicated lol
