Infnite loop error

Im confused as to why Im getting this error, hope someone can shed some light on what I am doing wrong.

Basically, the blueprint I created is the following:

As you can see its running fine without errors. It moves a door sideways using a timer.

Now I want to open multiple doors at once - so I want to add a second door on this timer:

For some reason it will throw an infinite loop, note: on the Sky_Sphere!, when I add a new actor get world loc to this script.
Removing the added components will make everything work again.
I have been stuck on this for quite some while, hoping someone can help me out.

Thanks in advance
