Major Crash (Reproduced!) in UE4.9

Hey. So I’ve got a reproducable crash which is stopping me from doing my project.

This is going to give you a headache.

And it’s going to give me one because I can’t continue until it’s fixed.


So this code here in a UMG:
60130-
is causing the engine to crash.

But the engine is getting confused. The log is saying time dilation is messed up, Even though there’s no code affecting the time in this UMG (Or firing anywhere near this time).

Right so @ looked into the log and saw the PhysXModules are crashing; Due to something weird happening.

The crash screen isn’t very helpful either.

Edit: Wise also says:
60142-
And here is the log, Because you wanted a headache when you saw this:

So I’ve been digging around and the code is crashing HERE:

Hello KitatusStudios,

I was able to reproduce this issue on our end. I have written up a report ( UE-21493) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. The issue that I wrote the report for was caused by the index being out of scope. You could use an invalid check to insure that you do not pass a null value into the “Scroll Widget into View” node. I hope that this helps. Thank you for your time and information.

Make it a great day

Thanks as always Rudy Inserts Heart Symbol
