Tesla balls cannot dust people near grounding rods

del: Tesla balls cannot dust people near grounding rods.
/🆑

- The tesla is SUPER deadly right now, anyway. If mildly charged, will
kill anyone unprotected. And people can STILL get dusted, even if
they've painstakingly set up a net of grounding rods.
- If you're hiding under only one, you're safe from the electricity and
dusting, but there are machines that explode all over the station. Only
a wide net provides any sort of cover.
- Basically, let's reward people for actually using grounding rods,
instead of getting RNG dusted if they don't cover in a locker for
however long it takes for Lady Tesla to leave.
