Expected Behavior

Altars: When shift + right clicking an altar, the amount of ME/recharge rate of ME should be displayed.
Cauldrons: Upon tossing ingredients into a cauldron with boiling water, the water will change colors and the desired item should pop out.

Actual Behavior

Altars: The amount of ME/recharge rate of ME is nowhere to be seen.
Cauldrons: The water changes colors (blue to purple to a brownish red), but no item appears. My altar is close by, and I have many modifiers on the altar and many plants in close proximity. Still nothing.
^^This occurs in Survival and Creative mode (even with a Blessed Alter and modifiers)^^

@Sunconure11 Nope! I don't think I've even heard of that before.
@Ayrion That doesn't seem to work for me either. Where is the power reading supposed to appear? In a corner? At the top?

Ah, I see. Here's what mine looks like:

Doesn't look like you've actually made the altar, right click it with a carpet

... so THAT'S what I was doing wrong. Don't I feel sheepish. Thanks for clearing that up for me! Now I need to try making something in my cauldron.

It worked! I finally got some chalk! Thanks for taking the time to help me out, y'all. Hopefully I won't have to come back with any more silly mistakes. :D

Do you have performant installed? If so, remove it. It causes this issue.

You don't shift right click on an altar to get the power reading, you just right click it with an empty hand.
