Auto-cannons - not keeping themselves loaded (needs testing)

This arguably could be considered "major" but I honestly don't know if any other player on the server would try building such a cannon as there are most likely no public schems, also the workaround is fairly simple. This also may or may not be related to the prior report From prior testing, when firing an OG-style auto cannon, it seems that the cannon doesn't keep itself loaded if no player is nearby. TNT/sand load chunks, and at least from testing on Sakura, cannons can keep themselves loaded if firing auto, but on this server, parts of the cannon unload, which at best would cause the cannon to stack less sand than it should, at worst will cause the cannon to blow up. This could be a result of instant sand fall but not sure (as sand "insta-falling" may or may not keep a chunk loaded) The workaround is simply to either remain at the cannon when firing, or if you want to move away from the cannon, have an alt or another player remain at the cannon.
