I have worked hard on making an amazing space-base, and I put in the custom ids for the oxygen sealer to work (Im playing tekkit so there are other mods). I put in the ids for the carpender's blocks, the inverted blue lamp, etc. I put the air locks on the base to seal it and then when I put the multiple seals down (5 sealers), It says "Area too big / Unsealed". I don't want to redesign the base or start over so I really hope I can fix this issue. The list of mods that I used (and put custom ids in for) are: Big reactors, Carpenders Blocks, and Project Red Illumination (Only the inverted light blue lamp).
