Thank you for the detailed reproduction steps, Greenwolf. I’ve placed a bug in for the issue under the number UE-26620. It seems that you have a workaround for now but I’ll be sure to let you know if any updates are made to the issue. There is one thing I wanted to mention however. If you’re packaging with Static runtime generation, the Invokers will not be taken into account.
As for the issue with the crashes when using Dynamic, it seems to be a project specific issue or at least something more complicated. I’ll need a copy of your project to look further into this particular problem.
