That is basically a bug. Certain actions (like Forage) get added automatically to your action queue when it is empty. If you remove Forage from the queue, it gets put there again.
I hope this isn't bothering you too much (you should be able pause, it is just a lot of micromanaging). The current version is only intended as a 1h (to 2h possibly) prototype/showcase. I am still slowly working on the game, but it takes time because I want to do it justice.
Also, I know that I have gotten things right when people stop having to ask "dumm questions", because every one of these questions shows to me that I haven't added enough Quality of Live and explainations to the game (or that there is a bug/unintended feature, like in this case) :)
