Inu Games - Modular Snap System Runtime

I think I found it. The problem is the “auto weld” physics parameter of the BP_PickupCube. Usually it’s enabled by default, but in the PickupCube bp it was disabled. So I enabled it back and now it seems to work also with the cubes you spawn on runtime.
To enable it, you need to open the BP_PickupCube, disable “SimulatPhysics”, check “Auto Weld”, then enable simulate physics again. Otherwise it’s grayed out.
