Research completed, yet mission goal not achieved

[Ole]

Hi there,

I am stuck with the silver star goals on the map Purmamarca. I have to bring a certain animal research up to level 4. I completed the required research to max level (during bronze star objectives already) yet the mission log says I am only at 2 out of 4 research levels. Does anyone know that issue? Restarting the game didn't help.

Thanks in advance :)

There is an option to further research animals at the top left (I think ) of the research screen, you can put a vet on them to "advance research" even after they have been fully researched.

Thanks for the replies. I am refering to the objective "Research Common Warthog to level 4".

Does that mean the common or advanced research? I already put a vet on advanced research for the warthog, but the objective doesn't update...
