UE4.25 crash on CreatureWidget drag/drop

[AsceDusk]

Hi, I ran into a crash in my 4.25.3
It occurs when I drag and drop a Creature Widget onto a blank canvas.

Something to do with a null CreatureManager? Am I supposed to initialise it somewhere in code?
From the video tutorials I simply downloaded the plugin and added it to my project, compiled it in Visual Studios and the editor launched fine. I can see it in the plugin list enabled too.

Here is the stack trace:

Hello,

That seems to point to no CreatureAsset was linked or initialized to it. Was any CreatureAsset loaded?

[AsceDusk]

Hi Chong,
No CreatureAsset is in this project at the moment. This is a blank project trying to just create a CreatureWidget. Am I supposed to have one in the project?
I have one now and I can try it again.

Hi @Chong,
The crash still happens when I simply drag and drop a CreatureWidget into a blank canvas in the ue4 widget editor.
I'm not sure what else I can try? Am I supposed to be initialising the plugin somehow? I'd assume if it didn't initialise that it wouldn't load at all?

The regular adding of a CreatureMesh to a plain BP Actor works fine and it even loads the json data and animates with the CreatureAsset.
But just dragging and dropping a CreatureWidget crashes the editor

Hello,

I just checked in an update, you can try to sync/pull from the Creature UE4 repo again.

Thanks

Hey thanks for the quick update. I'll be pulling the changes and checking it tonight.
