Sandbox mode needs a lot of work to compare to its predecessor. There are many game breaking issues right now. Builds will lose all collision, essentially making props "ghosts" that you can no longer interact with using tools- making any long term projects impossible. If you try to manually change values on some tools (using keypad to put in numbers in lieu of using the slider) the cursor gets stuck on your screen and hard locks you from moving or doing anything at all, requiring a full reconnect to fix. Facepunch please fix the OG gamemode.
