So I placed my turtle to offset a source block by 1x, 1z, and created a program which turns to face the flowing water block

The problem is, I set it to face minecraft:water (as that is what opening the lua prompt and typing turtle.inspect() returned), but for some reason directly after startup it returns minecraft:flowing_water. Every other call returns minecraft:water.

• Minecraft version: 1.12.2
• CC: Tweaked version: 1.86.2

To reproduce:

And screenshot of the setup

Minecraft returns minecraft:flowing_water when a block is undergoing block updates, and minecraft:water when it is stationary. For better or worse, this is part of Minecraft's game engine, rather than a bug with CC:T itself.
