I’m getting a crash when I remove a widget from parent, and looking into the log, I’m seeing that the specific error is the following:

[2015.04.09-21.18.20:195][422]LogWindows: === Critical error: ===
Assertion failed: ((UObject*)ContainerPtr)->IsA((UClass*)GetOuter()) [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.7\Engine\Source\Runtime\CoreUObject\Public\UObject\UnrealType.h] [Line: 357]
‘MyGame_C_0’ is of class ‘MyGame_C’ however property ‘TextProperty_47’ belongs to class ‘TRASHCLASS_MyGame_496’

Really confused what this Trashclass is! Any ideas? The crash is happening precisely when it is being removed from parent.

4.7.5 update appears to fix this issue.

For previous releases I was having this issue when the editor language was different from English, so by simply setting it to English was the solution for me
