Some things don't trigger all at once. (I think you have to make sure Mark's not at the gym?)
But maybe you're missing part of a complex necessary sequence. To have received the second jar, you must presumably have had Kate buy what she thinks are full rights to her room, meaning: done the money transfer, and returned home to find Nina in the kitchen, not only with documents to sign, but with a strange showdown there.
But .... maybe you have made Kate too reluctant to eat the honey?
It's odd stuff, that honey. Not only because of its apparently mind-altering effects on Kate, the experiences it gives her.
But also it's odd, that players are not sure when they've got it, or haven't got it in stock. Or whether to eat it, or keep it, whether eating it they lose it, waste it, or need it to progress, even if they lose it when they would like some for Kate later. Sometimes it's still in the "cupboard" of Kate's stock when you don't expect to see it. ....
I'd guess you need to let Kate have her latest experience, in her room - take the honey as a nightcap, and let her work through the latest set encounter with the otherwise departed Eva.
Then I think you'll find the solo meditation experience is also opened to her. (To Kate - perhaps not to Eva.)
