Mhm, there are some special effects from buildings that goes away by doing a recalc, usually caused by the effect being awarded through a python script rather than an xml tag with dll code.There are problems with CTRL+SHIFT+T function. I use it only when recommended (if it appears after loading game that DLL or assets have been changed after time when save has been created).
My civilization has city with Temple of Ptah that gives a free School of Scribes in every city. School of Scribes obsoletes (turns into Library) when Education is achieved. I have cities founded after Education where obsoleted School of Scribes was not given by Temple of Ptah.
After CTRL+SHIFT+T a Library appears in such cities.
There is some event - discovering of geothermal source of energy (I do not remember its exact name) that gives Power in given city/in all cities on the same continent (depending on player's reaction). Results of the event are gone after CTRL+SHIFT+T.
Low priority to fix recalc for these things, though it is good for us modders to be reminded about them once in a while.
