however, I've read custom timescales can cause some quests that assume timescale 30 to malfunction.
how common is that? I do agree that a slightly slower timescale improves the feel of the game, but if it can mess up quests it's a no-no.
also, it keeps me from being able to use diverse grasses, as their wind sway speed is geared for 30 and so they sway faster than the default ones, which looks horrible
