Hrmm I reported it on the previous build and was told it was a knowN issue and was expected to be fixed in the recent build
there are 2 ways around this previously
1 use the turnactions command in the ~ console
be warned this disables all warnings including idle ship and idle colony
2 use the unlock ( I believe ) command this will complete the entire tech tree and give you all the ideaology perqs but should now recognize that you are really done the tech tree.
