[2021] Stellaris DLCs not appearing in the game

kingsnake1996 said: I downloaded the game manually.

From where exactly, please?  

i have never heard of IGG, is that a grey market vendor or free site?

If you bought both the game and DLC fro GoG that should work of course. Is that the case?  

We cannot help with pirated games here.

Can we see proof of purchase for the game and DLCs from GoG please?
