Interiors of ships suddenly need significantly more oxygen to fill?

Hi

I noticed in creative mode that significantly more oxygen is now required to fill the interior of a ship. That must have changed with one of the updates 1.8.5-1.8.7, because I wrote down the values from 1.8.4. Specifically, it's about the ship MX5E and my version of it (MX5E-C):

Old values (1.8.4):
MX5E: 240
MX5E-C: 290

Current values (1.8.7):
MX5E: 263
MX5E-C: 360

How did this change come about? Unfortunately, I don't know which update changed this, because I only noticed it today. It is also strange that the factor of the values deviates significantly from each other for both ships.

I don't know whether this is only the case with ships or in general, since I only have these numbers from the SVs for comparison.

 

maybe cause of the "all blocks are airtight" bug that was fixed in last version?

 

Possibly. I've browsed through the changelogs of said updates and I think there are two possible updates:

1.8.5:

1.8.6:

Otherwise, the changelogs do not mention anywhere that the calculation for the required oxygen has changed.
