I did some changes in my local environment, then I updated the 'feature'.
When I try to deploy the change to another environment, but before I can start the 'revert' operation, some parts of the feature are marked as 'Rebuilding'.
The feature components are: - Field bases - Field instances - Strongarm
Additional details
I cannot use drush in the deployment environment.
This happened once in the past and it resolved itself after clearing the caches.
