What happens:

What you expected to happen:

The player picks up all items around him regardless of direction.

Steps to reproduce:

1. Drop items around the player in any direction
2. Charge some LP using Blood Orb
3. Enable Sigil of Magnetism by Shift-right click

Affected Versions (Do not use "latest"):

• BloodMagic: BloodMagic-1.12.2-2.2.12-97
• Minecraft: 1.12.2
• Forge: forge-14.23.3.2698

can we get that last image with the debug screen as well?

The player didn't rotate, so upper is north.
I deleted the test profile of Twitch App for the smallest-structured environment, so I'll remake the profile and take the screenshot.

Found the issue. For these lines you want grow not expand

expand(double, double, double) and contract(double, double, double) only increase and decrease the max values, respectively. They don't touch the min values. grow(double, double, double) and shrink(double, double, double) on the other hand, change both the min and max values to increase or decrease the size respectively.

PR in progress.
