I'm sorry if this is posted elsewhere...
I am fairly new to Salem and just build my Ore Smelter about 2 weeks ago, I have only smelted in it maybe 5 times and today while playing I loaded it up and began doing other things. Suddenly I head a crumbling sound as I swing my camera around I notice my ore smelter has disappeared. This is not the first time I have had things disappear but certainly the most expensive. Is this normal? should I prepare for my ore smelter to collapse randomly in the game?
Thank you
