I created a project in 4.0.2 using a Level blueprint, and an object with a blueprint, with an interface between those 2. I added the interface to the “implemented interfaces”. When pressing a key the level blueprint would send out a message which would be received by the object blueprint and then did a rotation on the object.
So far so good, everything worked perfectly.
Then i wanted to expand the interface, by adding a in and output to the interface, to give me the possibility to pass through a variable. At first the blueprint didn’t want to compile anymore and an additional _1 was added to the event as it was used in the object blueprint.
Now the entire project doesn’t want to launch anymore (both 4.0.2 and 4.1.0). I get the following error when launching the project with the 4.1.0.
We apologize for the inconvenience.

Any suggestions?
I tried to launch the project by editing the BaseEngine.ini, to see if this made it possible to at least launch the project, to no avail.
