I can confirm this is on the public_beta branch; my save is now locked to it. I wanted to throw in another data point. I decided to try it on my Steam Deck and I am not getting the same last issues, at least not yet. Hopefully that helps too.

Hotfix 1.2.176713
Since the latest version (1.2.176713), I have been getting extreme lag on all of my museums. It started on Pebberly when I placed a new exhibit, but has persisted through everything I've tried. I've removed/replaced the exhibit, saved and reloaded, restarted the game, and switched maps, but the problem exists across all maps. A new game in sandbox is fine. The game running at 2x speed is running slower than 0.5x when performing normally. If the game is paused, navigating around the map is fine, which makes me suspect something with the simulation. I've sent my saves into the support address, but I'm happy to provide more if I can.
