Hi , I don't know how to disable passive decay on hydroangeas in minecraft 1.12.2 (FTB Present Direwolf20 v2.5.0)

To be fair, it's also your choice whether you want to play the mod or not as is. If you want a change badly enough, fork it, find the line of code that makes it happen, tweak, and build

@macks2008 please stop bumping months-old issues with pointless comments

my apologies...

The answer is simple: You don't. Passive decay is there in order to push you to use other generation flowers and automate them for mana production.

okay , it's sad that this config is deleted , it's our own choice but okay
