hi! i am having this problem with building bug. i cannot see my workbench building. all the other buildings are visible except for this one. when i try to relocate my building i see that my workbench is somewhat there because of the blue tiles when you relocate building. but after i drop the building to relocate, the workbench is again invisible. it is irritating because i can not upgrade or arrange it because i can not click it. tried playing on facebook and i encountered no problem.
Um, take my word as nothing but a mere runts advice as to the fact that I know nothing but I would recommend clearing your cache, although before doing so make sure you have all data saved and that any saved game data is backed up through your account and not just from the compute. Otherwise cache clearing will delete that game data to.
Good Luck!
PS: This was just a random idea, sorry if it doesn't help
