Quick patch today — if you noticed your Board view buckets disappearing after restarting Obsidian, that's now fixed. The issue was a stale settings cache: when tasks were saved, the plugin could accidentally overwrite your latest Board configuration (like newly created buckets) with an outdated copy. Settings are now always synced from memory before writing to disk, so your Board stays exactly how you left it.
Grab the update and your buckets will stick around.
