ToME: the Tales of Maj'Eyal

At high speed, above 1000% or so, auto explore can flat out break and not work.
Getting high speed is easy if you want to test, Rampage + Movement infusion can easily break 6000%...

Played a b41 cursed recently and never found any problems of that sort... I'll try it with a Step up/Movement Marauder to confirm anyway.
