I think if the game crashes from a stackoverflow then NEC will not recover.
Original complaint:

Hi, so the mod's not working properly, i still crash out, this is the log https://paste.gg/p/anonymous/7b414be0b7bd483da4b41bb749659fab
i was making a bunch of runes with botania
game froze and i crashed out
it keeps happening after like every 6 or 7 runes in a row i crash, and NEC never saves me
its all the mods 7, latest version, and you can just use a guilty pool and a couple gaia spreaders and it takes like 2 or 3 seconds per rune, im making runes of pride
just have a stack of livingrock dropped on the altar, right click with empty hand to re-add recipe, and just making a bunch in a row
seems like looking away from the altar each time prevents the crash
