Hi team,

after conversion of my project from 4.12.5 to 4.13.0 some maps and blueprints can’t be opened.
When opening such map/blueprint the whole engine will crash.

This is the error report :

Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\Build++UE4+Release-4.13+Compile\Sync\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 833]
Array index out of bounds: 0 from an array of size 0

the crash happens on maps / BP’s where are no arrays :S

Hello,

I have a few questions that will help gather more information:

  • Are you getting a crash reporter window? If so, please provide your Machine ID from the window and ensure to hit Send & Close on the report.
  • Please provide the logs from your project’s Saved->Logs folder.

Thanks!

There was some update of the launcher, and surprisingly all works now. Thanks anyways
