I am just wondering if somebody else has encountered this/fixed it. I create new game engines with new research but I am unable to choose features (linear storyline et cetera) during the different phases of development.
When you say ‘Unable to select…’ do you mean that the options are there but unclickable, or that they don’t appear?
The former would be very much a bug, and knowing what platform you are running would be helpful in solving it.
As for the latter, make sure you remembered to include the newly researched features in your new game engine, and make sure you are selecting the correct version of your game engine when making a new game. I’m not ruling out a bug here, but sometimes it’s worth double checking things. With pictures if possible.
I too, have the same problem sometimes. The Feature has already been researched and included in the new game engine. However when you get to the development stage with the two columns, the one on the right doesn’t appear at all.
