Well... words referring to idiocy are only roughly 2% (by line % of total lines guesstimate, and similarly small percentage by symbol since they are all in symbol UNTOWARD) of the small language, but they are memorable.
They will show up more in anything that natively uses symbol UNTOWARD. I'm still not clear on which uses what. Symbols can't be just made up - it seems like megabeasts, for example, use ASSERTIVE a lot IIRC from my testing with even smaller languages (try only adding one or two words per symbol).
Can we only make additions to this if we sign up for a modding turn? I only want to do some minor things, such as add a little variety to metals.
You're free to suggest stuff without taking a turn. That's the idea. It's up to whosever turn it is to implement it. For example it wasn't mc's turn yet but his raws giving hangovers from alcohols were immediately added by Leibowitz. It should probably be more visible in the first post but I'm not sure how I could make it more concise, it just has such a lot of stuff that needs to be there. Fakeedit - ninja'd
(Pretty sure we have 0 types of clay. Of course if we can't redesign clay enough for it to be considered from scratch, so be it. I'm almost certain that's what's causing the ground to think it's everything sometimes though)
Unlikely. There's no special tag for soil about being clay. Vanilla clay is just a soil with [MATERIAL_REACTION_PRODUCT:FIRED_MAT:INORGANIC:CERAMIC_EARTHENWARE] - I don't believe reaction products affect where something should be placed in worldgen. That said, who knows for sure? But we did have BFEL's vanilla ripoff "clay" for a while and I think there were those small spots even then.
It could be something like, DF wants to make the very bottom of a different material than some other layers, this is not possible due to there being only "rock" and that
affects the surface in places. Or it could be something very simple we've overlooked so far. Incidentally, I did a little embarking on suspected problem areas (river deltas), and they were surprisingly made entirely of
rock in fort mode, even the surface. Todo: confirm one is a problem area in adv mode, then embark on that exact spot and see if DF setting the deeper materials in fort mode fixes it.
Underground vegetation was improved a lot by Leibowitz. But yeah, more stone, more metals, please. More everything would be nice but those are probably a priority.
