OI--234177 - Mealwood eating CO2, Bug or feature?

What does the room look like? If it has doors or wheezeworts then gas loss is expected.
 

Only has 3 floors of Mealwood, rectangular in shape, sandstone floors for the planter boxes, 1 tile of sandstone walls, no insulation, 1 garnet ration box, 1 high pressure vent (Iron), gas pipe (igneous rock) going through top wall, and 2 sand stone ladders. That's it, nothing else is in the room. Oh ya, manual lock on the top (Iron) gas pump in the other room is 2  tiles from the airlock.

Doors closing destroy the gases that they replace. This destroys the co2 you have

To verify - change the airlock door to waterlock and check if the issue persists

It does appear to be that the airlock was destroying a fair portion of the CO2; although it still seems strange that with 7 duplicates (1 a mouth breather) I'm still so low on Co2 without a carbon skimmer and have seen very little CO2 growth @ 90 cycles.

At cycle ~30 I was at ~250g of CO2, now at cycle 90 @ ~290g. This is without generating any other CO2 outside of the 7 dupes (I did return to the airlock save after testing the water lock.)

Just so you can guys can look at the #s I saw.. but if it's working as intended.. then I suppose all is good. Thanks for reviewing it.
