I'm really impressed that they patched it so quickly!...
Seems data Vexen, data Saix, quick run physics and the RC for timeless river are fixed... AND possibly a crash that has existed since the first Kingdom Hearts is also fixed. It has to do with Simba jumping at the end of a fight in KH 1, a streamer tried to get it to work, and Simba DID jump at the end but the game didn't crash so... maybe.
I'm really glad they patched it, but I DO wish they'd fix Xemnas' RC... there's no way they know about the bug with data Vexen and DON'T know about Xemnas RC being broken
