Using a clean environment with nothing but Brewery, the DrinkListener fails to recognize the brew here.

Steps to reproduce:

1. Setup a server with nothing but Brewery
2. Do "/brew create Fine Beer" and drink the item
3. The player gets fire resistance.

Error:
[Brewery] ERROR: Database failure! unable to find UID -2 of a custom Potion!

Uh thats bad..
Probably because the ConsumeEvent in the DrinkListener1_9 and in PlayerListener are both on MONITOR. So its unclear which one is being called first.
The PlayerListener removes the brew so when DrinkListener1_9 is called after that for it cant find it.

Seems legit.

Dont set the base potion to Mundane, just replace the potion when drinking.
Tested and works on 1.9.2

Do you remember if this was an issue in previous versions for 1.9?

I didn't notice it at all. The issue has been posted at SpigotMC and I had my IDE opened, so I tested and debugged a bit. Aber warum zur Hölle schreiben wir überhaupt auf Englisch O_o

Keine Ahnung, vielleicht will ja jemand mitlesen :D
Ja danke, so konnte ich das schnell fixen.
Würde dann jetzt die 1.4.4 releasen, vielleicht kannst du es noch eben schnell bei dir testen wenn du Zeit hast?

Erledigt. Es funktioniert prima :)
