I am having a strange problem with loading blueprints that contain references to the leapblueprintsupport plugin, and wondered if anyone else had come across the issue.
Basically I can create a blueprint, add leap specific functions, save and compile and run fine. I can keep doing this during the first session of the editor. If I shut down, then restart the editor, an assert fails in Blueprint::ChangeOwnerOfTemplates, line 972. This is firing because the ComponentTemplates list has a single entry which is a null. I don’t really know enough about the internal workings of this class to fix this, but wondered if anyone else had come across the problem?
EDIT: patching the engine to skip this error, I can get the editor to load. I then get a load of errors about loading /Script/LeapBlueprintSupport. I have confirmed that the plugin is still checked in plugins. Any ideas how to debug this?
