as far as I understand, if you modify the state manually (remove some resources), they are not managed anymore by pulumi (regardless of the fact whether they still exist or not)

what did you try to achieve?

so I exported the stack

deleted the resources

and imported it again

but the resources weren't removed when I looked into the pulumi console

did you run

pulumi up

after all this?

I had to add some hardcoded resource IDs and run pulumi up a few times, to get things in the correct oder

and not the cloud resources

what I did was

I deployed a resource, but because of a bug, it was missing some inputs that I needed to delete it anymore

then I exported the stack and tried to remove the resource from the pulumi stack

then I imported the stack again, but the import command said, no resources are affected

and in the pulumi console, the resources were still in the stack

then I rewrote my dynamic resource provider, so it had the missing inputs hardcoded

ran pulumi up every time I changed the hardcoded values for the next resource to delete etc.

now the resources are gone from my stack, but I'm still confused why I couldn't delete it with an export/import
