[ICML 2026] Scores increased and then decreased!! [D]

hi,

one of my reviewers initially gave 4(3). addressed his concerns during the rebuttal. He acknowledged it and increased the score to 5(3) with final justification as well. checked open review randomly now, I can see he reduced it back to 4. am guessing he did this during the AC reviewer discussion? is this a sign of early rejection? My average was 4, which has now reduced to 3.75. do I still have any chance? Any comments would be appreciated.
