Me too 😭. The order is on board, but Maklo did not cook, even though I've set his cooking priority to high. I think this early Access is bad than the Demo

Try to drag and drop him in front of the task icon. Sometimes it might force him to do his job, but will not fix it permanently.

I've noticed that sometimes it says I have enough items in the supply crates. But when the merchant comes and I want to pack up food, the crates are actually empty. Unfortunately, I haven't been able to solve my Maklo problem yet either :/
What also bothers me is that they tell the employees to go and collect, then they shake the trees, but they don't pick up the fruit :/

Same with me. No one is making Gustav's order. I ended up restarting the game which resulted in Gustav no longer sitting at the table, and no order to make, even though I'm still on that quest. Seems like I'm stuck.
