A known issue, but I don't really know what to do with it. Should it do nothing? Should it grab a honey bottle with a chance to destroy the fluid? Because it can't just act like water does and give infinite bottles as that'd break so much balance...

I can think of three possibilities:

1. no interaction at all
2. 1/3 chance to destroy the source block
3. different fluid states on the source block for how many bottles have been taken

I vote no interaction (or my proposal at the bottom). If someone wants to bottle honey from source liquid, they should have to:

• go through a tank
• use a cauldron
• craft it normally

If we have an interaction event for a single bottle, it would have to be:

• custom functionality (eg. differing source levels)
• unfair/accident-prone (only get 1 bottle for a single source)
• RNG
  -- none of which are fun.

Another option, which is slightly saner, is requiring the player to have 3 empty bottles in their hand. This would bottle all 3 and remove the source block.

Ooh, I actually like the concept of three bottles in hand!
