No Buzz Increase

[Sontine]

I am still on the first museum, on the 1 star objectives. I am trying to unlock another POI by getting 175 buzz on fossils, but for some reason no matter how many decorations i put down or buzz bonuses i get i seem to be stuck at 150. Is anyone else having this issue? How do i fix it? Or am i doing something wrong? Any answers are much appreciated! Thank you!

Do expeditions for more Fossils. Then place them. That's it.

Its get a total of 175 buzz on fossil items. So dropping in more fossils items will do the job.

Make sure you're looking at fossil items. This does not include frozen items, prehistoric (amber) items or dino bones.
