Spawning a Collision Box on top of the player, Collision Box Begin Overlap triggers twice

Development Programming & Scripting Blueprint

I started a new Third Person template project to reproduce this issue. I have two actors, one called “PerminentBox” and one called “TemporaryBox”. They both have identical box collisions.

Here’s the BP for the PerminentBox

I plopped the PerminentBox into the level and walked over it… and the output



LogBlueprintUserMessages: [TemporaryBox_C_0] Overlap Begin Overlapped Component: TemporaryBox_C_0.Box Other Component: ThirdPersonCharacter_167.CollisionCylinder
LogBlueprintUserMessages: [TemporaryBox_C_0] Overlap End Overlapped Component: TemporaryBox_C_0.Box Other Component: ThirdPersonCharacter_167.CollisionCylinder
LogBlueprintUserMessages: [TemporaryBox_C_0] Overlap Begin Overlapped Component: TemporaryBox_C_0.Box Other Component: ThirdPersonCharacter_167.CollisionCylinder

For some reason, when using a trigger box to spawn another trigger box, the second trigger box has a Begin Overlap trigger, then an End Overlap and then another Begin Overlap.

I tried this by having the level blueprint spawn the Temporary Box on top of the player and this issue did not occur (just did the one overlap).

An idea why this might be happening?
