When I place my last line of Ender IO capacitor banks (normal and Vibrant confirmed, likely Basic as well) using an Iron Wand from Better Builder's Wands (unknown if the same bug happens with the stone, diamond, and/or unbreakable variants), the capacitors are permanently tainted. The game freezes, after about 2-3 seconds all sprites disappear leaving you in an empty void of sky, and then 2-3 seconds later it crashes. Upon booting it back up, getting too close to the capacitors will cause the same sequence to occur. The only way I've found to fix it is to get rid of the capacitors. It has happened both with an 8 by 8 square and a 6 by 6 square. Error message shown below.
