Build work being undone

[NotoriousGIB]

First time I thought I imagined it...but no, it happend again...so I built a load of the superstructure of my latest wip and twice now, when Ive gone back to it, all the work has gone.



A known bug? It is now



prebuild 0.121 + hotfix

Should not use pre-builds for building if not testing anything.
But yes, in this specific build there were some savebugs and chunk errors, yes.
