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
