Hi, I somehow reproduce this issue in a simple way.
- Create an empty Entity named “child” and make a new template from this.
- Create another empty Entity named “parent” and attach “child” to “parent” as a child entity and duplicate “child”, then make a new template from this.
- Duplicate “parent”. At this point, duplicated “parent” has 2 “child” which has diff “+child/-child”. (there is no diffs on “parent” entity, but 2 diffs on “child” entity, I don’t know why)
- Do “REVERT ALL” to one of “child” entities. You can see “child” entity deleted on the “parent” entity that is NOT duplicated.
- Delete the “child” entity which is on the DUPLICATED “parent” and which you did “REVERT ALL”.
I think you can’t delete any entity after these procedure.
