The foundations I was concerned about when I made this thread are gone.
I achieved this by dismantling all the connecting foundaations to the structure and then just built over it with the new grid. On the next server restart the foundation changed state to abandoned and then decayed.
However, I now have another foundation in a different part of my base that is more stubborn. I have dismantled all connecting structures to it yet after 4 server restarts it still lingers. This foundation however only took up 2 spaces on the new grid so instead of laying foundations over the top (prevented by clipping). I have simply put ceilings over it instead.
There is a slight difference between the foundation height and ceiling height, however it’s the best option I have right now. I wont risk keeping the base derendered in the hope that the single stubborn foundation changes state to abandoned without losing my entire base as that is a bit too much to lose over a slight difference between structure height.
A possible work around for this would be to simply turn friendly-fire damage on for structures on PvE servers. Fire having the ability to destroy stuff under the terrain would be the most ideal method of solving this problem, if only PvE players could use it.
It confounds me the amount of baby bars that are in place for PvE players… - no pet or thrall friendly fire, no structure friendly fire etc…
Do they think just because we don’t like having our beautiful designs destroyed by trolls that we need our hands held this much? This is supposed to be a survival game dammit!
