I can't understand some things with the hidden grottoes (I'm using version 9.96.4):
where do I see the "grotto number" for a certain grotto? the encounter tables don't give them a number from 0 to 19. they also aren't numbered in the order listed there, because I read that someone RNGed ditto (giant chasm) and put 0 as the grotto number, but in the tables the giant chasm is the 10th one.
what does "open hollow" mean? an empty grotto? if I have to RNG, for example, in grotto number 9 and all the other grottoes are occupied, what should I put in "open hollows"? 'cause if I put 1 (since the only unoccupied grotto is number 9) it gives me and error.
last thing, I noticed that all the results are at frames that are at least "initial frame +3". since I read that it's better to use one that is at the initial frame, so you don't have to worry about advancements, why are there no such results?
thanks for the help.
