In the "Short order" quest, I am supposed to put down "Roast leg of lizard" -- but there is no hotspot where I can! All other tables have a hotspot, just not this one. Is it a bug or am I doing something incorrectly?

If this is the mission where you have to bring out the 4 orders then you should be able to put it on the table. Note, that there are 2 different pies (not sure if that is the lizard one) so make sure you grab the right one. Then just take the small steps up and put it on the table. Hope that helps.

That unfortunately doesn’t help — I cannot put anything down on the table; there is no hotspot (“Put down” text does not appear).

So you were able to put the other 3 plates into their correct place, just not the "lizard" one?

Correct.

Interesting. Sounds like maybe a bug. Do you have an earlier save where you can retry (maybe change the order of putting the plates down)?

I’ve only used quicksaves for the past few days of playing, unfortunately…

Ah, I'm often guilty of this myself. The problem now is that if it's game breaking bug you would have to do a complete restart. I would in the future use the save game slots maybe once a play session... but I know that doesn't help now.

I reported it to the develpers and it is now fixed in the latest 6.55 version!
