graves, chairs, doors and such are hardcoded, i don't know if it can be done.
i uploaded 2 more files after that, we're currently at 32. you should download it too, try and compare it with the previous ones and we'll see which one is the best.
making blunt/clay stones should be possible, but why do you believe wooden ones should be effective? wood is generally light (therefore horrible for blunt damage) and can't take a proper edge(therefore horrible for edged damage).
EDIT: i looked at the creature raws a bit, and i have a few ideas about the castes:
SOLDIERS: when i got the wasp raws, there was a 1 to 10 percentage of soldiers/ workers. i changed it to 1 to 2 in order to make early military easier. but now that we added powerful war beasts, i wonder if we could change it back to 1 to 10, make them gain an experience bonus to military skills and have an experience penalty in civilian skills. that way, waspen armies will be a mixture of elite soldier troops, war bugs and worker ranged levies. mighty if built and maintained carefully, and not too difficult to assemble.
WORKERS: workers should form the backbone of a colony: the only ones capable of unpenalized civilian labors, but small and fragile in close quarters.
DRONES: for now, the only special thing drones have is that they're male. after the reproduction overhaul, they will be reduced to disposable slackers, whose only responsibility will be to fertilize eggs to produce more useful hive members. and yes, i know this is not that far off from real life drones, but we're talking about a civilization here, not your typical wasp nest: why not make them have an actual role in waspen societies? for instance, they can have a small bonus in social skills. that way, you will want to keep a few as mayor/broker/psychiatrist and not just send them all to fertilizing duties.
QUEEN: just like the drones, the queen is just an egg producing factory as of now. if she's supposed to be such an important part of the colony, shouldn't she have more responsibilities and talents instead of just being the fertile female? i can't think of anyhting yet, just saying...
GENERAL: for flavor reasons, max age seems a bit too much. i would imagine most wasps to have a relatively short lifespan (40 to 50 years maximum) with the exception of the queen which should be much more long lived (maybe up to 500 years, it doesn't matter at all in fortress mode anyway). finally, i know i was the one to suggest it in the first place, but on hindsight NOEMOTIONS may be a bad idea: tantrum spirals are an integral part of the game, and that will remove a source of FUN, as well as any reason to seek and cultivate the wide variety of plants they have at their disposal, exotic brews, pets, et cetera.
anyway, tell me what you guys think about it
