What happened?

After creating some Just Dire Things fluids in world, which you need to do as part of the ATM Star, when you pick the fluids up with a bucket, it just turns to water again. The Dire Things sensor also cannot sense what the fluid is when it is in the world, it thinks everything is water.

I can confirm this has happened with the following liquids
Polymorphic Fluid
Blaze Ember Fluid

i have no yet tried it with the others

I am unable to reproduce this issue.
Picking up polymorphic fluid does give me a bucket of polymorphic fluid.
