Got a tree that keeps regrowing and clipping into base and destroying the walls it touches. Chopped it down, placed foundations/pillars etc over it and it still keeps coming back. PVE server.
Went on my usual official PvE server earlier and while the single pillars and foundations do seem to have the short timer on, I noticed that people seemed to be bypassing that by just doing 2 pillars ontop of each other...
