No reward for completed quest

Good evening

Today I level up my Nors civ. to lvl 25 and Markus Pollux (Empire bazar in every capital city) gave a quest which was instantly completed just by accepting it (a celeste quest whit 4 chests, building blueprints for capital city (roman legionary statue) and maybe something else - don´t remember). I completed the Revard as usual but I didn´t receive it in my inventory - I just didn´t get the reward and I had well enough space for it.
Thys isn't the first time this happened to me. The first time it was whit a Egyptian guest from Princ Sesostris (I think it was the first one in Nunibian Expansion - escort priest unit across the map). I selected the item I wanted (There was a choice.) completed and I didn´t receive anything in my inventory.

Can anyone please help?
