## Bugfixes

| Area            | Fix                                                                                                                                                                                                                             |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| IKO             | A widget or search result list that could not retrieve its data now says so and offers a retry                                                                                                                                  |
| Building blocks | A final building block can be deployed to an environment that does not allow drafts, such as production                                                                                                                         |
| Form flows      | A form flow that has been used can now be deleted from a draft case definition or building block, as can the draft case definition itself; its form flow instances are deleted along with it                                    |
| Case list       | The case list now loads even when a ZGW API fails to return data for a case, for example when the zaak is confidential and GZAC is not authorized to view it; the affected columns stay empty and all other data is still shown |
| Cases           | A form opened in the side panel of a case stays open and keeps its contents when switching between the case's tabs                                                                                                              |
| Cases           | A start form configured to open in the side panel now opens there on every case tab, including tabs without a task list, instead of opening in a modal                                                                          |
| Platform        | The application stays stable when users reload or close their browser, instead of slowly running out of memory                                                                                                                  |
| Platform        | A user with a slow or lost connection no longer delays the processing of cases and tasks for other users                                                                                                                        |
| Platform        | A user closing their browser while a page is loading no longer shows up as an error in the application logs                                                                                                                     |
