I ran into issues with putting buckets with fluids in them into the /dank/null/.

1. The fluids place above the block you right-click on (or one block above the expected placement spot if there is a block there).
2. The buckets aren't affected in any way, leaving the fluids in them when you use them.

How to Reproduce:

1. Put buckets with fluids in them into a /dank/null/.
2. Use them, and observe the issues mentioned above.

I was in Survival when I encountered these issues, in case you were going to ask.

This was a WIP feature that I thought I had disabled lol..I'll get it fixed in next update

so it is still disabled..but only vanilla buckets..i'm pretty sure the issue you're experiencing is due to the bucket being a forge bucket aka the Universal Bucket..fixed in dev..thanks for the report :)
