Hello, it seems the problem still exists in 4.25.
Generally we use this approach: (for example we want to attach/detach the player to a vehicle)
- Calling AttachToActor in the player BP and supply vehicle BP as parameter.
- Calling DetachFromActor in the same BP with parameter to vehicle BP.
This is not working, although seems only in specific conditions (maybe if the target actor already has attached another actors).
The “opposite” logic fixed the problem for me: I changed detach logic and called DetachFromActor from the vehicle BP with the player actor as parameter.
