RFTools v. 1.10-5.62

I was using a Builder Block to clear water & lava from a quarried area and noticed that the water was being cleared but not the lava. Tested on a much smaller area and I can't get the Builder to clear even a single source block of lava.

Sorry, it was using a Shape Card (Clearing Pump) which was configured by using mark mode, shift-clicking the card on the Builder Block then selecting the 2 corners of the area to be cleared.

When I noticed that it wasn't clearing the lava from the initial large area (32x32x60 blocks) I set it up again with a test area made of dirt in a 3x3x3 shape with a hole in the middle and a single bucket of lava placed there. I'm activating the Builder with a lever. I've just tested it again and it definitely isn't working, unless I've just got something wrong in how I'm using it.

Edit: Just to add, I've tried it with both "Single run and stop" and "Keep running with redstone signal" modes and it makes no difference. Enabling the preview mode clearly shows that the liquids I'm trying to get it to removed are within the configured area.

Can you give more specifics? What card is in it? How is it configured?

Hi, I have the same problem with "Molten Uranium" from "Immersive Engineering"
I treid the same things.

Make sure you have the card shape set to Box (solid)

Yes, use 'solid box' instead of just 'box' as the latter only does the outline

Not clearing lava for me either in Foolcraft pack. Solid block, even triple checked the dimensions. Even did preview mode to verify I set the pump clearing card correctly.

UPDATE: Not removing water either.

UPDATE 2: Ended up being an issue where the builder block doesn't work with the EnderIO tanks. I put a drum on the builder block and it immediately started working.

Ah known problem and this is a problem in EnderIO. Not RFTools
