When you add this mod in a pack, it makes every modded fluids unplaceable by the player, the issue is fixed when you remove the mod. I'm using latest forge version.

I'm Also Having This Issue. Tested Liquids (Buckets) From Silent's Mechanisms/Mekanism/Security Craft/Create And None Of Them Is Working When This Mod Is Used.

I am looking into this

Basically, i take any buckets from any mod (per example Molten Iron Bucket) i click on the ground with it, nothing happens, like the bucket was a simple item. It prevents the player from placing any liquids on the ground except vanilla ones.

Can you give an example?
