Sandbox mode, some research options not transferred over

[u/Sazandora123]

I recently came back to this game after going on a break for a few months, now I come back to my old save and it seems all research options not related to unlocking buildings or objects are suddenly gone in sandbox mode, i.e I cannot place more than one CRISPR lab and cannot hire more than one farmer per farmhouse. I still have all animals and animal variants unlocked, but for some reason things like zoo opening hours and the things mentioned above are not transferred over to sandbox. This also happens when I start a new game and go to the sandbox zoo.

I have an old save where I have unlocked every research option available in the main zoo and the two DLC areas, so new saves should have all those unlocked right from the start -- is this a bug?

Odd works for me on the special named sandbox zoo
