# Bug fixes

- Gantt Module/Resource panel - changing aggregation if Effort mode is set to Original estimate causes application freezes
- App verifies and modifies all links descriptions without checking dependency mappings
- Gantt - Moving the task that is excluded from scheduling causes an error
- Gantt: box is not loading when grouping is active and some dependency has no source/target task summary. Cannot read properties of undefined (reading 'summary').
- Scope definition - There is no avalaible sub-scope configuration on Iteratiion level (does not always occur)
