Beware that this bug might have affected the selection of observations that I pushed recently to the “unknown” observations projects mentioned above:

Beside losing data, providing wrong data is the worst thing a server can do.
I will not check if I really got wrong data in cache, I just discard everything I got from the 12th december, by restoring a backup I made, by chance (in principle, I trust the server), on 11th december 2022. I will not do anything for checking observations already pushed to the projects. Just be cautious before concluding anything if you find some irrelevant observations in these projects.
