latest.log
I no longer have Vanilla Refresh and that mod does not add any blocks at all. I keep getting this spam and I'm at my wit's end because it seems totally disconnected from any real cause, it'll just show up randomly.

Something I've noticed is that this log spam happens when I don't get the message that AP logic is enabled, meaning it's unable to load. Either causing the issue or just being affected by it. I'm not sure. After an embeddium chunk loading crash the log is no longer be spammed. IDK

The Placeables mod doesn't have a community or issues forum to troubleshoot, so here I am for at least this mod and I've asked in VR's discord.

Eehh it's probably because i removed a mod that adds tags. It is weird that AP reads mods that aren't active anymore though.

This log spam is entirely unrelated to Additional Placements. You have loot tables in a mod or datapack that reference missing blocks.
