I don't know what it is, but I can tell you it is neither the ratio nor the temperature.
I needed dinner anyway, so I made a small experiment. I made half a batch of crust using the ratios from your recipe, and baked it in three small tartalette pans. I used butter so soft that I had to spoon it out, I couldn't cut it (it sits on the counter as a rule). The water was also room temperature, it had been sitting for 1-2 hours in the filter jug.
For the first tartalette, I placed a small ball in the middle of the pan and pressed it outwards with the fingers. Beside giving it a worse-looking shape, this made sure I had no additional flour sticking to the surface. I didn't roll it between sheets of foil, because it was too sticky for that. While I am probably more experienced at crust baking than you are (but by no means an expert), I purposefully disregarded the usual advice just to exclude the possibility that you missed something of it.
The second and third one, I rolled in sufficient flour to not stick, so the surface had quite a bit more flour, which I figure could bind excess butter.
Then I baked number 1 and 2 straight from the counter, as-is. No preheating the oven, no docking with a fork, no filling in weights or beans. The third went into the open ice compartment of the fridge, which hovers about 0 Celsius (but isn't cold enough to keep ice in a plastic box from melting). I baked that one after a bit over 90 minutes, by that time the oven was cold again. The crust was solid.
The left lower one is the "press with fingers" crust. The lower right one is the one which got floured and baked immediately. The upper one spent time in the fridge. The foto is not perfect, but I can tell you that none is greasy, and none has pooled butter.
This is another phone camera picture, this time of the unwashed pans directly after removal of the crust. None of them contained a visible pool of butter, although it was obvious all three have been in touch with fat. The constellation is the same as in the above picture. The lighter stuff you are seeing is flour, not chafed teflon.
The only difference I saw was that the non-floured one had some obvious tiny (pinhead sized) bubbles of fat while baking. Nothing large enough to drip, and it did not look unpleasantly greasy in the oven or afterwards.
The crusts are crisp and nice, nothing moist or soft or greasy about them. (Using "greasy" as perceived fat content here, because of course they are full of butter, and an experienced cook can tell it).
My conclusion, whatever happened, it was not the fault of the recipe, neither was it the "didn't cool" part. If it was due to too much butter, you must have also mismeasured something by a significant amount.
