Node is causing BP to be corrupted/uncallable

This is a new bug in the 4.11 Preview, it did not exist in 4.10. If you place this node in a blueprint:

Even if it’s not connected to anything, just floating around, you can’t call any functions on that blueprint any more.

Here you have a repro project: Google Drive: Sign-in

If you hit “1” then you should see a print from a blueprint. You don’t see it. If you go into that blueprint (Cube Blueprint) and remove that node I talked about, it will work.

This bug only occurs in standalone and packaged, not in PIE, so make sure to not test it in PIE :slight_smile:

Hi John,

I have reproduced your issue, and have entered a bug report (UE-27269). Thank you for your report, and for providing the test project. I will provide updates on this issue as they become available.

Have a great day
