The Bob Wonder starts at +300%, the extra 120% is due to level bonuses from buildings in adjacent tiles. (each level bonus to Bob is worth +10%). (My Bob is getting +12 levels from adjacent buildings).
ALL of my other Core Worlds "only" get the +300% bonus to their base research production from Bob, on their worlds.
The Bob Wonder also gives a +3 level bonus to buildings in adjacent tiles that do research. (see screen shot below).
This shows why the Bob Wonder needs to be changed. It is probably most over powered item still in the game (in it's present form). Although there are some other pretty powerful items as well.
In case you never noticed it, it has been there for at least 2 Months (maybe longer, version 0.60 or earlier).
You have to research Strong AI Tech to get it. Start by Researching Weak AI and go through another 4 Techs to get to it. I think that it is the 4th Tech after Weak AI Tech going up the tech tree branch.
I first discussed the Bob Wonder about 11/16/2021 (Nov 16, 2021) in the Discord, about 2 months ago.
I have built it in every game that I played long enough, since then.
