After the update that changed how LIGH is cloned, the lightning now goes much farther, making it destructive and useless. It broke at least 10 of my saves (most are deleted now).
It was fixed, I think, because lightning from clone was intended to be just like lightning from tesla coil. There have been some complaints, but I haven't been able to find where this is impossible to work around, so it hasn't entirely bothered me.
The way it works now is much better, it's direction is even affected by all types of gravity. I think a good compromise would be that it gets stopped by void, making it useful in the old way again, which was what it was most useful for.
