Hope this is patched quickly. It has to be one of the most frustrating bugs in recent memory. Practically every stair or slab i place when building high i'm having to place, break, place, tripling the time it takes. It is enough of a pain that i finally created a new account to vote for it.
Thanks for your hard work!
I have recently experienced this issue as well however my steps were a bit different. I cured them before ever linking to a workstation or trading.
