The items are in the null, and you can pull them out, but they aren't visible.

This first image is of me putting in some netherbrick.

This image is from three seconds later, after I closed and reopened the null. You can see in my hotbar that the netherbrick is in the null, but it's not visible in the UI.

Another issue I noticed is that OreDictionary wasn't functional for logWood, but it's possible that's a feature and I didn't realize it.

Please keep it as one bug per issue.

Need to know which Dank Null version you are on.

Alright. I am on version 1.7.94
A little more messing around, and the issue only seems to occur while connected to a server. Being more specific, the items only disappear from the UI when there is more than 127 of them.

Don't need mod list. Can replicate when only dank null is installed. More wondering if this ever worked on older versions.

It doesn't just disappear if it's just over 127 items. I have a stack of 292 stone that shows as 36 items. It seems like some stack counting mechanism is broken. Also on version 1.7.94

Yeah, I'm getting the exact same issue. Same version too, plus 1.12.2-14.23.5.2847. 128 blocks and above breaks the rendering.

It's also interesting to note that the Dank Null seems to think that a blank-rendered item is an unoccupied slot. So it's possible to place an item in the blank spot where a block should be rendered. After closing and re-opening the Dank Null, the new item is in the correct spot, though.

@DoctahSawbones: Could you share your mod list just to see if we have a mod in common? Might at least help us determine if it's another mod interfering, at the very least.

My mod list's here.
