Nice little problem that looks morpho but actually isn't if you rock over your left foot enough. Exit through the right slab not the easier left one. Feels a bit soft for the grade, but might depend a lot on conditions.
Rain sucks, but broken holds suck even more. Remember, never climb on wet rock in Fontainebleau.
The sandstone becomes brittle, and pulling on it will ruin classic problems. Drying it doesn't help, because it's still wet and weak inside.
All you can do is wait for better conditions.
