I play in english, but when you get the work task to survey wildlife, the tooltip on the task specifically lists the waterfall as an option, but if you go to the waterfall there is no option to do so. Here is a screenshot https://imgur.com/a/jvuSSM4
The pictures are very helpful. My first thought was that the task to 'survey' might be unlocked at the next career level. Then I realized you had completed two of the three actions of that task. Did you try taking a sample at the waterfall?
No, it doesn't work. I have gotten a task on a different day to take samples from the waterfall, so it's a separate action.
Luckily survey does appear in all the other places listed, so it doesn't prevent you from completing the daily task. It's more of a minor annoyance than game breaking.
Conservator's nature career has a bug. Tasks to do at home are not adopted to sim career level. Similarly as in the career of a scientist. However, in the career of a scientist, you had several tasks to choose from. You were able to advance if only a few were completed. Theoretically, there are no similar such tasks in the conservator's career. However, this problem can be dealt with in two ways. One way depends on the player. If he sends out research data to the Institute, he will increase his career level. The second way depends on EA. If the "send data to Institute" is added to the to-do at home list, players will stop getting nervous when the task once again completed will not be approved by the game or if he does not have such an option in the game as above.
Data can be obtained by probing for example plants in the garden of the sim.
