Missing buildings after down time.

hey there i jsut logged on and after the down time i am missing 2 buildings. a fresh coal mine and a lvl 2 marble mason. Was this just me or was it a comon thing. i can understand the coal mine but that marble mason was there for a month, Its like he became part of my family and now hes gone... He will be missed. :(

I had the same type of thing happen over a month ago. Was only a lvl 1 mason and would have probably been torn down anyways but it was still interesting to see it had simply disappeared one night.
