Version: 10.4.0.2498 Mode: Tested creative and freedom (new game for both), did not test on survival. Mode: Singleplayer SERVER NAME: Not applicable SEED-ID: 0 (creative), 305337 (freedom) MODIFIED PLAYFIELDS: No Reproducibility: Always Severity: Minor Type: O2Rooms Summary: Some forcefield sizes say they are airtight but are actually no longer. Description: Tested in a base cube and CV cube forcefields of size 1 X 1, 1 X 2 and 1 X 3 remain airtight, all other sizes show airtight in the description but depressurize a room if used. Steps to Reproduce: Build a cube (CV or base), add fuel and O2. Remove blocks on one wall and add one of the larger forcefields. Try to turn on oxygen in the room. O2 shows on half block around the Ventilator but not in the room. Remove the forcefield and replace with hull blocks and the room is now airtight.
I think the issue occurs only when you place them horizontally. Edit: I placed this 3x5 in the middle of the room. The airtight "collision model" seems to stay vertical.
