What it is

⚠️ Oops, a little oversight in the mstatus.sd field could lead to confusion! It doesn't update when mstatus.fs is set to Dirty — like ignoring a flashing warning light on your dashboard! Think of it as a restaurant where the chef keeps preparing meals but forgets to update the menu to reflect the ingredients used. Without that update, diners could be led to believe they’re being served something fresh when it's actually not quite right. This oversight could result in unpredictable behavior within your system, potentially leading to stability issues. While there’s currently no known exploitation, having outdated information could cause confusion or malfunction in your processes. We want to keep things running smoothly!
