Vaultbreaker - missing EGG (Cryo coolant) on first vault

Hi, we came to first vault - 02, we had batteries but EGG was missing. It never happened before!

Is it bug or is it intentional?

We went for the EGG, powered it up, opened main doors but didn't pickup Vault-data because of timelimit. We are low level players, one of us played Vaultbreaker for the first time (game chat). 

It seems to me like Bungie is changing "variables" each day. Vaultbreaker was playable for the first 2 days. Next days it was difficult - too many tough enemies, too less security keys. Yesterday it was easier again and today that EGG was missing. Maybe difficulty is set according player levels. I play usualy with players lvl 20-40.
