Hello, and thanks for taking your time to look here!

I have issues with items within my modpack not stacking whenever they are picked up or mined, but after a few seconds I can stack them properly like normal. It's not the NBT data.

If i mine some stone, some blocks will stack normally, but others occupy their own seperate slot. I can then organise it manually, but it's really a hassle to do so. It's likely a problem with one of my mods, but I haven't been able to find a solution online, or any similar experiences with helpful responses.

I'm playing on 1.16.5 and Forge 36.0.14.

Here is the list of mods:

Thanks again for your help!
