Mansion Comments: Leofani Manor

[pleomax]

Once again, like before: Leofani Hard 16301: I am not able to get the red key. What am I missing? Neither I get it when the blocks are silver nor when they are gold. I cheated a ittle bit in the Mansion builder and saw that there is a passthrough from 16301 to 16302 in the upper are of 16301. But to reach this way to 16302 the three blocks leading

upstairs

should be silver in the middle of the room. But the entry to these three silver blocks is blocked by the silver column at the right of the room.

Any hints welcome!
