Same issue here on 5.4.4. Only development builds crash when loading into a map, shipping builds were fine. In our case it was also a decal component attached to a base enemy class. Most of the enemies inheriting were just fine, but one started crashing builds. Deleting the decal component in blueprint and readding it in c++ fixed it. I would have never thought to suspect the decal in the enemy if it weren’t for this post. Like I said, we had many types of enemies inheriting the same base class and most were just fine.
