I've put together a mod and I'm ready to upload it, but I noticed something in TES5Edit.

Could anyone tell me what this means? I'm referring to the fact that it says 'compressed' in the info window. The only changes I made to that cell were placing two objects outside Vlindrell Hall. It seems to be the only cell that has this change.
