So I’ve done these steps:

1. Open any BP;
2. There’s a little arrow faced downward near to “Compile” button, press on it and the list’ll show up;
3. Go to “Save on Compile” section and choose “Never” (in case “On success only” is already being chosen, otherwise choose “On success only”);
4. Go to that section again and choose “On success only”;
5. After all previous steps were done, make some minor changes (add any BP node or move some, it doesn’t really matter what to do - just make some changes, so you’ll be notified by a “star” appearing next to the name of this bp in the tab);
6. Hit “Compile”;
7. Congratulations! The editor should have crashed after successfully following this instruction.

It’s not really a problem, but I do think that this is a bug, so I report that.

Hello,

I have attempted to reproduce this crash, but I have not experienced it on my end. What operating system are you using?

Windows 7 Ultimate (64-bit).

I can record you a vid with steps, that I’ve done to make the editor crash.

Thank you for providing the video. Can you reproduce this same crash in a clean blueprint, or is it only happening in that particular blueprint? I tried it in a basic actor blueprint, but I did not receive any errors.

Hm, that seems like a kind of strange behaviour of the editor/engine 😃

I even made a completely new blank BP project and this happens:

Hello,

After some further investigation, I have discovered that we have two bug reports in our system (UE-27856) and (UE-27509) that relate to the issues you were experiencing. Both of these are reported as fixed, and the fixes will be available in a later version.

In the meantime, I recommend saving manually after each compile to avoid running into any issues.

Have a great day
