In some cases after undoing a replace actors the position of a BP actor is incorrect.

Not a regression from 4.10.4 CL-2872498

In QAGame place an Actor instance of BP_Variable
Alt-Drag to create a duplicate
Select Blueprint Class ContextMesh in content browser

Note that instead of the 2 BP_Variable actors being at the correct position, they are both back at the position of the original
