As of 9-14-2017, it's important for players to upgrade any twig buildings they may have to avoid the new twig decay feature. Once you place a foundation or foundation wall you will have 7 days (1 week) to upgrade it to at least wood to avoid decay. This feature is to improve client performance, reduce world clutter and ensure future plots for future players.
