No real blunders here, just different opinion at best.

Even though Black is down a Pawn, he has enough compensation with his Rook activity as well as Bishop opposite color.
24.e5 fxe5 25.Bxe5 Rxa2 26.Ra1 Rxa1 27.Rxa1 Rd5 = 28.Rc1 Rd7 29.Rc5 Ra7 = I think the players are just playing on to make move 30. I do not see serious chances for either side to score a full point in this game.
30.Rc7 Rxc7 31.Bxc7 Bc2 32.Bxa5 Bxb3 This is a drawn position. I don't expect the players to continue this position much longer.
As expected, the players agreed to a draw here.
