I used the ms_arbiter autoflag all mines function at my rng manipulation runs.

My Expert run with this method got accepted.

My Intermediate run didn't.

I think this is legit, because in normal RNG manipulation runs you also know at the start where all mines are.

Your runs didn't get accepted beacuse you used a ms_arbiter cheat "auto flag set at game start". Replaying boards IS allowed, but using cheats is not.

hmm... ok
