Sandstorm hurts player when inside known airtight greenhouse
Not a Bug
Sandstorms somehow are able to get into greenhouses that are known to be airtight with no leaks and hurt the player when helmet is open
I've attached an image of me inside greenhouse and the vent status showing it being airtight
I've uploaded my saves. The latest one is in "Plot filled"
I have the same bug 
I just want to add to my OP that there are no sub-grids involved here.

Hello Engineer,
Thank you for reaching out to us on the forum and for providing the world save file.
We tested this issue on the “Plot Filled” save, and the character appears to be taking damage not because of the sandstorm itself, but due to low O₂ (oxygen) levels inside the airtight space. While you were indoors with your helmet open, your character was relying on the room’s O₂ rather than your suit’s O₂ supply. It seems that during the sandstorm, the doors to the room were opened, which depressurized the space and left it with low O₂. When the doors were closed again, the temperature stabilized, but the O₂ level remained low since the air vents did not refill the room. Staying in a low-O₂ environment with the helmet open causes health loss, which is the expected behavior. However, with the helmet closed, the character’s health will no longer be affected.
In addition, please note that sandstorms reduce breathability. You can read more about this in the Environmental Effects section of our Survival Guide - Weather. As described there, both light and heavy sandstorms reduce breathability by 50–75%.
We’ll keep this thread open and are happy to provide more information if needed. If you encounter a similar issue in another scenario/case, please send us that particular world save only (ideally vanilla (unmodded) world save file where the issue occurs).
Thank you for your understanding.
Kind regards,
