Wanted to save people some weekend confusion if you're using the G train shuttle at Hoyt-Schermerhorn. The permanent-looking sign on the mezzanine still points you to the Bond Street exit for the Manhattan-bound / Court Square bus. Ignore it. The actual stop has moved from the old spot by the newsstand to Schermerhorn Street, midblock between Bond and Hoyt, on the south side next to the church railing. I watched a crowd of maybe 15 people stand at the old location for two full cycles because the bus doesn't stop there anymore and the yellow "shuttle bus" arrow is still painted on the sidewalk.
What makes it worse is that the stop itself is marked only by a small paper sign on a lamppost, and it's blocked from view by a parked box truck half the time. The bus drivers know, but they won't pick you up if you wave from the old corner; they're under enough pressure on the weekend shuttle and the supervisors have been telling them not to make unlisted stops.
If you're coming from the Manhattan-bound A/C side, go upstairs like normal, walk past the token booth toward the Schermerhorn exit, but instead of taking the first staircase up to Bond, keep walking to the second staircase. When you hit the street you should be looking at the church, not the parking lot. The stop is just west of the intersection by the rent-a-car loading area. For the Court Square direction from the Brooklyn-bound side, same block but across the street, and that one is actually signed a little better.
I know it changes with each phase of the work, but this past Saturday and Sunday it was consistent. If you're making a transfer to the L or the 7, give yourself an extra five minutes until you learn the new spot.
