Fixed.

Cool. What happened there was, sometimes a patch was downloaded but not its recursive dependencies.

Moreover, there were two async tasks in parallel before my patch: one to download the patches, another one to apply them, with rate limiting to avoid bothering the server needlessly.

I fixed that to include recursive dependencies, but then that’s a third task, and that task changes the order between patches, introducing their dependencies in the communication pipeline between the tasks.
