Someone who moving water with chisel and bits I really have no clue this what they said LOL:

How did it cause a crash?
I was just using this setup```

```what were you chiseling```

```Water```

```I was actually moving the setup to a compact machine```

```chisels in the machine ?```

```Yup```

The only possibly null value on that line is the fluid that the tank is being filled with.

I have to say that seems like a bug with XU2. I can't see how a filling a tank will a null fluid should be possible.

I just realized I'd committed a change for this almost half a month ago. There was still no release for it. I went ahead and added a test to cache the error, even though It seems more a problem on the other side. But less crashes in my code the better.
