I should add that this isn’t consistent.

Sometimes editor crashes on duplication, other times whilst it sort of has duplicated but being asked to be renamed it crashes. Exactly when you create a new variable etc in editor.

Also result of crash is inconsistent. Sometimes a BSOD others just editor crashes.

Hi pwsnow,

This is a known issue, reported here:

It has been fixed internally, and it should be working in 4.7 Preview 4 if you’d like to check it out.

Many thanks ,

Apologies for post then.
