Just built the endless research park, it was a major investment, only to have it do nothing.  No dust bonus, no science bonus, and no +25 happiness bonus.  Yet in a previous game it worked just fine, science went way up after it was built and the tool tips correctly listed its effects on dust/science.

I did a little more testing,  save/reload/restarting the game and processing a couple more turns didn't help.  I do notice that I am getting a +25 happiness bonus but it's from the Obelisk of all space time,  a thing that I very much have not built. 

Just thought of something,  other people have been complaining that happiness is currently broken and not applying its bonuses, Endless Research park only gives research and dust bonus when happy or above.  My system is at 100% but perhaps the happiness requirement isn't triggering the effect of the building properly?

Another game, another functionless wonder that only gives a +25 "all time space" bonus rather than the correct endless research park bonus.  

I saved one turn before the wonder was built,  you can load the save, hit next turn, and compare the yields.  No science boost, no dust boost.

Hello and thank you for your report!

I've tested this on my end and the bonuses are granted as intended so chances are it's already fixed on our side :)

Regarding the issue of happiness coming from the wrong improvement, you were right - I'm fixing it as we speak.

Cheers,
