Hidden updates, new requirements.
They appear to have done more recently,than would seemm to have been mentioned on the forum.
Whatever they have done seems to have created more bugs than have been reveiled already.
Things previously unlocked are now locked again,causing problems.
E.G.
It is telling me I need to build lumber 1 in order to be able to build a manor, but then tells me there is no room to build lumber 1.
Already have above level 1 lumber.
