I can’t remember if this was posted previously, but on Testlive US3 PvE server, frequently when I press the “play” button on a craft station, it instantly consumes all the fuel needed to instantly craft everything in the craft station inventory, that is in the craft queue.
This also applies to the thrall wheel. I had 3 thralls cooking last night. I just now logged in and I wasn’t sure if they were completely done, so I clicked the play button and watched about 400 gruel vanish.
Also, I made the mistake of trying to store 300 gruel on my follower thrall. I checked her inventory a few minutes after storing on her and it was all gone.
