I have a multibody part that has mirrored sheetmetal features.


Within the mirrored feature there are two extra derived bends and a persistent rebuild mark. I can suppress the derived bends (this improves the performance of the part significantly and removes the rebuild mark) but I cannot delete them without deleting the mirror feature. 


This is a legacy file, so the model it at an end state, I cannot simply delete the mirror feature and rebuild the failing features as I didn't do the original modelling. 


This file is a bit of a lost cause but I would like to raise awareness of this bug in the hopes a fix is developed. I have a colleague that was experiencing performance issues in a file with the same error.


For some reason (and this could be attributed to deleting parts earlier in the feature tree) mirror features a allowed to contain "ghost" derived bends from deleted bodies or features, or they can generate their own erroneous derived bends.
