I tried to replace the bp_item base with older and clean version of it but i still getting the same error while packing

We’ve come across the same error. A thread for a similar error pointed out issues with circular logic, but we’ve packaged before without getting this error and the only difference we’ve made is adding Print String debug nodes.

Working in 4.13, I am getting a crash that leaves me unable to open my project on the next time I go to open it (it works fine until I close it, but will corrupt with next open). This seems to happen anytime I have an actor or component reference one of my enemies and need to select the class from a dropdown menu. So creating a node (even without connecting it) for SpawnAIFromClass, or GetAllActorsOfClass, or having an Actor reference as a property in a bp will all cause the project to crash on …

At some point, our error started crashing Unreal any time we would try to open a Blueprint. Then it stopped and now the error is seen only during cooking/packaging.

Any help is appreciated!
