Summary
On the Steam platform, the “Magnets” achievement is supposed to trigger only if you complete the game WITHOUT using a compass. This appears broken as I used the compass extensively and it triggered anyway.
Seed
N/A
Settings
Extensive use of custom islands. Mods active: Palm Grow and Increased Stacks.
Steps
Cannot replicate as achievements are a one-time thing, however, a simple check of global achievement stats will show that the exact same percentage of people who have completed the game have also gotten “Magnets” indicating that it is broken.
