If the construction script of a parent blueprint calls a function within a child of that parent in the construction script, compiling the child blueprint will cause the parent blueprint to incorrectly show in the level viewport until it has been moved to re-run the construction script.

This was initially reported in [Link Removed].

Regression? (No), issue (does) occur on 4.10.4

Steps to Reproduce
  1. Download, unzip, open attached project
  2. Open A_Child
  3. Press Compile


Parent blueprint in level is reset, cube above sphere disappears. Moving the asset re-runs the construction script and re-applies the child function.


Blueprint compiles, Parent actor does not change in viewport.
