So I went through Omega 1 Savage for first time and after many attempts i finally cleared but I didn't get the Datalog due to not having inventory space. So its probably my fault in the first place for not checking but not being able to go through it again to actually get the datalog is kinda frustrating. I do a lot of crafting and gathering so my inventory always get full so I'm sorry for not always checking. So I want to suggest that the loot you earn should at least go into the mail if your inventory is already full.
