Issue Description:

Fluid conduits and Pressurized fluid conduits will disconnect from the tinker tank, as if not identifying it as a valid container. i've only noticed this happening when exiting and re-entering a world. The pipe will re-connect if it is updated, such as placing/breaking a block next to it, or pressing a button infront of it.

What happens:

Trying to connect fluid conduits to a tinker tank, some conduits will disconnect upon leaving and re-entering the singleplayer world, while others seem to work just fine, with no real indication as to what is causing it.

What you expected to happen:

I expect the pipes to stay connected.

Steps to reproduce:

1.create a tinker tank?
2.hook up some conduits to it
3.exit and enter the world
...

Below are images of conduits on the tinker tank, displaying the randomness of whether they will connect or not. Before exiting the world and re-entering, all conduits in the image were connected to the tank and would work without issue.

Known bug in Tinkers. Their (multi)blocks change their connectability without telling their neighbors about.

Easy ingame fix is to cause a block update to the connection (like placing a block next to it).
Not a permanent fix, unless you can cause an automated block update everytime the server (re)starts.
