[xplodr]

So I was searching on a way to reset sleeper's tomb and I tried to input a query but I accidentally missed out on part of it ( I was too tired to be messing with this stuff). I wrote:
update spawn_conditions set value = 1 and zone = "sleeper";

it said query OK, 39 rows affected. I don't know what it actually did but I want to put it back however it was lol any ideas?

Also in case I was on the wrong track, does anyone know how to reset sleeper's tomb?
