I believe it tries to evolve whether or not enough candies are available.
When there isn't enough candies, it shows that messages

[Plotin]

That's a good explanation, thanks. I'll keep an eye out for that and close the issue in the meantime. Enough open issues as it is ;-)

Not working.

As this seems to be a bug after all, I am reopening it

The option to evolve after catch will soon be removed. Please use the EvolvePokemon task to handle your evolutions.
