[LLQE] Royal Enovy does not arrive at Magnolia Park/Not winning chess

I had the exact same experience as spanz12 - I went to the park (at night because I was playing a vampire sim), the envoy appeared, I played chess with her for ages (with 10 logic + focused) and the objective never completed even though the board kept getting reset. The sun came out so I had to have my sim leave and come back when it was dark again, but now the envoy won’t appear on the lot again, in this or any other of my saves (which is usually how I solve any blockers). The envoy has not moved into a house in any of the 3 saves I tried. I tried creating a new save, and the envoy doesn’t spawn in households at all after waiting a full day.

ETA: After trying the new save, I was able to call the envoy over to my sim’s house on the very first save I tried it on and suddenly beating her at chess at my sim’s house took 20 sim minutes and finally progressed the quest. This notably did NOT work yesterday, so I don’t know what changed. I also have no idea if it’s supposed to work on the home lot, but give it a shot if you can get her to show up, I guess.
