Updated my server to 1.4.0, another player joined the game, and immediately the server crashed as soon as his base loaded in. Checked crash reports, ticking tile entity, a Sushi-go-crafting fermenting barrel that was located at the other player's base. Enabled Forge erroring entity removal, server started right back up. He joined, the barrel was still there, but could not be accessed. He broke and replaced it, still no access. He tried making a new one and ended up with a client crash as soon as he crafted the new fermenting barrel. Crash report here. Will also pass along report to SGC dev.
