A friend (no seriously) currently has a choice between two guild master plots but we're short a bit of vital information.

Someone has told us that the GH that comes with the master plot can't be deconned. I've been hunting around looking for info but can't find anything solid other than a few old forum posts saying you need to build a GH on the master plot before others can build anything on the sub-plots.

It's of particular interest because the GH on one of the plots is not ideally positioned and if it can't be moved it makes that plot considerably less attractive and her decision a bit easier.

Does anyone know for sure how this works?
