Ok I'm not able to make it happen but if you get it again see if you can spot what the worker was doing at the time. Thanks
well I told the worker to go pick up a crude worker and put it in the recycling machine and set that on repeat. I happened to have a crude worker in my hands at the time to go and recycle it myself but the worker picked me up and I couldn't get him to put me down. I traded with him, put myself in my own hands and my character sprite dissappeared, so I saved then loaded and that was when the game broke
