update to MC 1.17 and official source mappings
add copper ore to default config under working mans minables
introduce new configurable UI overlay for finder needles
New configuration options and defaults:"onScreenPositionWidth": 0.5,
You can configure position and size of the needle overlay, and whether or not the player has to have the compass in his hand or offhand, or if it just being in the hotbar is enough. The coordinate system starts at the top left of the screen, so 0.25, 0.25 would be in the upper left corner for position. Configuration is read just once per game launch, FYI.
I suggest you delete your old config and let it re-generate (back it up first if you have custom needles to keep).
The needle configuration itself has not changed. But the "feature" IDs have (stronghold, fortress etc)
Here are alternate values which put the Needle overlay over the offhand item:
