Open [1.2.2] Egg timer going down while inside pc

[KipDoesAThing]

After completing a digilair run, i put the egg i got from it into my pc still while in coop and close my game after that, later going into my pc i see that the egg i put there has its timer set to 0.
i've recreated the glitch already twice on purpose.
