Hey thanks for another 5 stars! Yes at the moment it is normal for the drink to be applied instantly. (I couldn't actually get the plugin to work so I had to re-write it, hence some feature changes)
v2.0.1 should be a big update with the plugin being able to hook into BreweryX, aswell as being able to have the drinks added to your inventory instead of being consumed instantly (unless inv is full) + a few more features.
If you've got any more suggestions, please feel free to pop on over to my Discord server!
