Officially addressed
Official demo notes provide the strongest basis for changes, including control, Grab All, and optimization work. Build context matters.
Community-reported
Backpack behavior has community reports but incomplete scope. Reports remain labeled until their sequence and reproduction rate are clear.
Not yet a known issue
A confusing mechanic or one unreproduced event is not automatically a bug. It starts as an observation another player can test.
Write a useful report
Include build, platform, hardware when relevant, location, inventory state, exact steps, expected behavior, observed behavior, and restart results.
