To reproduce:
- Start a new game with default parameters
- Open the blueprint library, select a saved parametrized blueprint
- Place the blueprint, this opens the configuration dialog
- While dialog is open, double click outside the configuration GUI: this moves the location of the blueprint under configuration, and opens a second configuration GUI (If the second configuration dialog is moved, we can see the previous one below)
- Either cancel the second dialog or validate the configuration, this does not seem to matter much.
- If the first configuration dialog is validated, the game crashes.
If I try to change the configuration in the zombie dialog, the game also crashes.
Attached is the blueprint I've used to reproduce the issue, but I suspect this may happen with any parametrized blueprint that has multiple parameters (a single parameter blueprint does not seem affected).
