I just tested it, and it seems that your suspicion is correct. This only appears to be a problem at the Spice Festival (it was on the buffet). I tried it at a regular food stall, and my Sim finished it without any problems. Will update the first post and title with updated information.
EDIT: Updated!
I'll re-test at the festival .. when I get one
Gosh, I just realized how hard this can be to actually test. The food stalls that show up by default at the Spice Festival do not sell siopao, so the only way to get it is if it's on the buffet, and even then there's no guarantee that it will spawn, since the items that spawn on the buffet are completely random.
It does. So this may be on testing for a while 😉
Just got the festival and can dupe this. I'll add on the next round
Oh thank goodness it isn't just me! This is totally bizarre, though. I have no idea what would cause this one food specifically to be an issue at the Spice Festival. I don't think I saw this happening with the other foods there. 🤔
