SM will not get any nerf in the scole of this PR or thread. Speaking about dangerous - this just sets a limit to the Tesla, otherwise people would just be able to leave PA on max level and go their ways, making Tesla balls grow indefinitely which I guarantee will eventually lag server and might even cause server-wide freeze/lag.
This PR will set a limit to balls that will depend on your setup, 1 grounding rod can handle 4 miniballs. And it will also make sure people don't leave PA on level 2, plus it actually add the only other way for Tesla to escape(which works literally same as singulo because like skull said these are singulo type engines).
I do not think it is a nerf as now that miniballs were fixed, the max amount of power generated by Tesla with standard setup can be up to 4 million W, but you would have to monitor it.
