FancyFluidStorage Version: v. 2.0.3 for minecraft 1.10.2

MinecraftForge Version: 12.18.3.2422

Client or Server?: I'm using ftb beyond with this installed into it so i'm not sure if its a client or server but the crash report says server but i'm playing singleplayer.

Crash Report (via. Pastebin): https://pastebin.com/0qGw653P

What happens / happened?: whenever i break a tank valve it doesn't get removed only becomes a ghost block and after a few tries to break it the game crashes.

How can we reproduce it?: I'm unsure as it only recently started happening and there was nothing wrong up till now.
