Problem Description

Locked, yet empty fluid drawers will accept any liquid entering the drawer controller they are attached to.

Expectation: Like storage drawers, a locked fluid drawer should not accept any liquid even if empty.

that's strange. I'll check it

Thanks for mentioning this old question, I didn't find out the reason for the loss of lock until today. I will upload a new version in a while. It is worth mentioning that I changed the texture model by the way, so it will take a long time.

I created 2 pull requests (one for each version) that fixes this issue.
hope it helps.

thx for the mod.

thanks iamshift' efffort. I was busy in the last six months so that can't deal with the issue.

But the problem still occur there due to the lock mechanism of StorageDrawer and my misunderstandings.
And Now I think I have came nearly by the truth.

For the player, there is a way to make the drawer enter a special state. It's locked, but it's not locked. In-game it appears as a constant lock (doesn't respond to using a key for it, or flashes past it), and it's the same during NBT's inspection process.

I have known the problem before the issue with the help of a kind player in the Discord channel of StorageDrawer. But when I solved this problem, another problem came out.
So the drawer is locked, it's actually an illusion.
I may sound like I'm speaking in a riddle, but that's what it is.

But in fact the key is valid, but I can't find a better way to find out the truth for the time being.
So actually, it just looks like it's locked, it's not. Of course, if you right-click once with the key, you can actually lock it. This is the answer.
It will take a while for me to continue working on it, and can't fix it just yet. But I have to explain the situation in advance.

It will be fixed in the next release.
