[Scenario issues] Borderline fever

[muerteFR]

I am in the process of translating this scenario and without testing it, just by launching it (with the official version of December 8, 2024), I get these 2 errors below.
When clicking on a DB button another error appeared. Given the size of this scenario, I imagine that there must be quite a few small bugs. I don't currently intend to test it in depth but if I find any other errors while quickly testing it, I will point them out following this issue.

a. Just by starting the scenario.

b. when leaving the game.

c. Many errors appear in succession when I click on a GM button.

d.
