Sky Factory 4.0.2, MC 1.12.2, RFC 0.1.84

I've noticed an issue with client crashing when an action involving a fluid folder causes the player to swing. The most prominent examples are when a player is removing a fluid folder from a liquid cabinet, or when changing place mods on a folder in hand via sneak+swing. Both of these actions often, but not always, cause a client crash with an NPE @ onEntitySwing().

One such crash log can be found here: https://gist.github.com/dualmoon/831852feb73667a5e659719019b722e6
