Hello,  
I am testing a project, development configuration, launching on Android. The map loads and crashes shortly. I attach [one build, deployment, and run log][1] which includes the assertion failed under consideration:

```
Assertion failed: (Seconds >= MinValue().GetTotalSeconds()) && (Seconds <= MaxValue().GetTotalSeconds()) [File:D:\Build\++UE4+Release-4.15+Compile\Sync\Engine\Source\Runtime\Core\Private\Misc\Timespan.cpp] [Line: 136]

```

I noted the timespan functionality in blueprint appears to lack features and present some shortcomings. I have identified the blueprint

Any help would be much appreciate to get the node corrected and/or the bug fixed. Please let me know if you require any further information. Thank you in advance.
