Probably not something easily solvable, but putting belts and a chest as so: And walking to the left against the chest results in jittery motion.

I'm using bob's mods, however I don't know what they do to collision.

Oh, good to know it's fixed, thank you!

Suppose I build an L of pipes like this: If I drag my mouse from the top left most pipe, down one tile, and to the right out the other side, I place extra pipes erroneously. I'm using a jetpack mod, however I don't think this should interfere with pipe placement.

Wait, if I understand it, there're three fluidboxes: Source, Pump, Destination, and it costs energy to move from source to pump, and from pump to destination, no?

If that's the case, then its buffer should be filled with enough energy to move from source to pump and pump from destination in a ...

Wouldn't making the energy buffer be enough to fill the fluid box, and pump all the fluid out be a fix?

I was designing a very fast water train loader, and I happened upon this design:

Providing power and a fluid wagon to put water into creates a very jittery display when hovering the mouse over one of the pumps pumping the train:

In the gif, it looks much less ...
