I recall this being a thing in previous versions of Reliquary, but in the 1.19.2 version of Reliquary, I can no longer hopper items into a pedestal that has a void tear on it. I can still pull items out of it, though.

This works correctly for me.
I assume you haven't tried inserting into empty void tear, right?

I will need more detailed steps how I can recreate this.

I made a couple screenshots below. The void tear has several stacks of oak logs in it. I'm trying to put more in it via hoppers -- both hoppers have oak logs in them, but they don't feed into it. But if I put a hopper underneath (and fill each slot with oak logs so it doesn't pull the tear out of the hopper), pulling the oak logs out works as expected.

turns out the bug was that it didn't accept anything once it was on or over max stack size (so usually 64) and that bug was there for a very long time since forge made a change on their side like 5 years ago. I have fixed that in the latest release.
