I was deconstructing stuff when factorio froze, as if stuck in an infinite code loop.
I created a savefile seconds before it happens.
This is the second time it happens to me, also with deconstructiong stuff,
but I don't know exactly if it is the construction drones mod, or the belt balancer mod.
I don't remember what I was deconstructing the first time ( days ago ).
This is the savefile:

I looked into it, it is the belt-balancer mod that is causing the problem,

There is a loop-de-loop in his on_nth_tick handler:

You should send the save to him to investigate,

Thank you very much, for your helping in finding the bug. I fixed the that bug with version 1.1.7 and 2.0.3 :)
