May 16 at 8:18 comment added Hannes Jakob Thank you very much! Do you know perchance why this is still listed as one of the problems, despite other problems being updated to show their resolution?
May 16 at 8:08 comment added Chris Lambie-Hanson To see why $FP_\kappa$ fails after forcing with $\mathrm{Coll}(\omega, \omega_1)$: work in $M$, and let $\dot{f}$ be a name for a continuous, increasing map from $\omega_2^M$ to $A_\kappa$. Then we can find a single condition $p$ that decides the value of $\dot{f}(\alpha)$ for cofinally many $\alpha < \omega_2^M$. But since $\dot{f}$ is forced to be continuous, $p$ actually decides the value of $\dot{f}$ on a club, so we have a closed subset of order type $\omega_2^M$ inside $A_\kappa$ in $M$ itself, which is a contradiction.
