Hi André,
Ok so I managed to repro and fix this issue and another issue which caused some components not to generate at all
Those fixes are now in UE5 Main branch and will be part of 5.6 but if you need to integrate them sooner here are the changelist numbers:
- 41640252 : Fixes some components not generating at all with hierarchical generation
- 41651040 : Fixes your deadlocked state issue
Hope this helps and sorry for the issues.
Thanks again,
Patrick
