Describe the bug
Ceramic buckets don't insert their fluids into Ex Nihilo: Sequentia's wooden or stone barrels.
They can extract fluid from a wooden or stone barrel and can both insert and extract fluids from the crucibles.

Versions (please complete the following information):

• Minecraft: 1.16.5
• Ceramics: 1.6.3

Other mods required

Using the modpack ModColonies version 0.10.4
Ex Nihilo: Sequentia: 2.0.2.7

Bug in Ex Nihilo, they are not using the forge system that makes it work with custom fluid containers. Nothing I can do to fix it without hardcoding to that mod.

Darn. After looking in Ex Nihilo's issues they said they are going to fix it either.
NovaMachina-Mods/ExNihiloSequentia#201

but its not fix, i have the same probmel

i don't have this problem myself, maybe another mod is causing the compat between ceramics and exnihilo

As I have stated, my bucket use the forge system to work with other mods fluid tanks. They work with many other mods including Tinkers Construct and Thermal Expansion. If they do not work with a specific mod, that mod needs to fix it, I cannot fix it.
