Unable to get research completion - 174/177 max.

Finished all the researches, including nuclear and DLC, saved the game, checked the save - preview says 174/177 research done. Double-checked - every single node is done, absolutely nothing left.

Probably a result of the changes to research que, like new saves starting with farms rather then it being a research.

Thought the same, and if the cause is that the game was started before the patch, then it is OK, but if after-patch games have that too, then it is an issue.
