@Vou-II(View Post) Did you create that using the normal brush (but large size) with TESC selected? TESC won't work very well if you created it a different way - e.g. using replace mode or with console.
In the beta I noticed the new element of TESC (Tesla Coil) That produces another new element LIGH (Lightning) produces cold LIGH. Why? Why doesn't it produce hot LIGH? I've also noticed that the LIGH from TESC makes any element it touches (apart from itself) heat up, Even PRTI, PRTO and WIFI!
