For Loop error , using Add ChildActorComponent

Development Programming & Scripting
1

Hello, I am trying to make a spline blueprint, contains looping coins on a spline (see pic 01), and when I use “Add ChildActorComponent” to add a blueprint call “Blackcoins” (see pic 02), the maps will crash and can’t play .
My question is how can I fix this error, or any other “Add Component” I can use instead of “Add ChildActorComponent” ? Thank you!

Here is the error message:
Renaming an object (BP_Blackcoins_C /Game/Maps/UEDPIE_0_L3_TestLevel.L3_TestLevel:PersistentLevel.BP_Blackcoins_C_2870) on top of an existing object (BP_Blackcoins_C /Game/Maps/UEDPIE_0_L3_TestLevel.L3_TestLevel:PersistentLevel.BP_Blackcoins_C_2873) is not allowed

Hi Gor,

I just reproduced your blueprint in 4.5.1 and it works fine. The issue you are seeing maybe fixed if you update. Could you try it with a cloned version of your project?
