I was doing some experiments on DEUT bomb, with some victims made of VINE/PLNT and METL.
Occasionally I found some O2 moleculars around some PLNT survived the explosion, while I DID NOT placed any O2 You know these's no way to make O2 from other particles, the only possible reason I could imagine is that the PLNT produce it
Then I tried to do it again, flood the PLNT, give light, heat it, but never see any O2 again
