The coolant cannot enter the carpenter.
There are hot coolant in the carpenter tabulation but no coolant.
modpack version:1.9.0

Sorry,I don't speak English.
So it can only be described through translation software.

But it can be made in version 1.7.1

Show me screenshot of what you trying to do.

1. Can you reproduce it in new creative world?
2. Does it work if you put liquid inside with a bucket?

Neither 1 nor 2 can be achieved.

1. 你能在新的创意世界中重现它吗？
2. 如果你用桶把液体放在里面，它能用吗？

No matter how it is used, the coolant cannot enter the carpenter.

I started the game today and found that I can make it now.
I don't know why.
Wishing you happiness every day:)

I always love when issues fixed by itself😁
