Since the last update, controller players can't eat seeds anymore. The action will show mapped to the appropriate button, but when you press it, nothing happens and the prompt disappears.
Edit: even worse, you completely lose the ability to interact with anything until you move the inventory cursor off the seed when this happens.
Steps to Reproduce
Get some seeds, try to eat them with the controller
Get some seeds, try to eat them with the controller
