Comment 10 for bug 536149

I can confirm this bug.
In the attached savegame is just build a goldmine. After my miner had become a chief miner, i upgraded the gold mine to a deep mine.
The chief miner entered the mine and filled the second slot for the miner. The chief miner slot stays empty.

No other mines built, only a warehouse. Perhaps the chief miner entered because he was nearer in the warehouse than the miners in my hq?
