Here's a thought

[malicious bloke]

on MoO2, Aquatic races treat terran and ocean worlds as Gaia environments...

and Tolerant races treat all planet types as Terran...

So if you have both, does that mean your race automatically treat every planet as a gaia?

Tolerant does not have that "Terran feature". It was removed before release (but still left in some descriptions). Look here for the exact numbers of a tol-aqua combination:

Tolerant
This Pick means that you can use 25% of the surface additionally. The only exceptions of this 25% bonus are Terrans, since here only 20% of the surface was unused, as well as Gaias, since the entire surface was already usable on this planets.
