Lost several builders to fire elementals because I was building an ancillary near the corruption. The problem was, the builders were going over to the ancillary, doing one build action, then walking over to a graveyard nearby over in the corruption and punching it. This provokes the mobs inside to come out and swarm whatever is attacking it(I've been sniping with ballista towers so far). Besides the obvious undead, one type of creature that can spawn are fire elementals. These are dangerous. The only practical way I've got to kill them is to godpimpslap them into a nearby lake and watch them fizzle and die like they deserve. ...Which requires them to walk out of the corruption because I can't use god-powers on things inside it.
I think I finally rage quit when one of my most experienced builders, who was also heavily pregnant at the time, died and then reanimated as a zombie because she died in the corruption.
Rise to Ruins. Supposedly you can resurrect your dead, but that requires their ghost to appear, which I haven't seen yet. A quote from the developer from about a year ago says that ghosts will (almost) always appear during full moons(when seasons transition) but also randomly other times. Not sure if that will help poor Derpy Lassius(orig. Derpy Hooves but she got married) and her corrupted fetus zombie baby.
EDIT: Just remembered the one I wanted to post instead of the one above.
Saw a screenshot of someone getting swarmed by a death-stack of AI-designed ships. Using the screenshot, I tried to make a design based off the ships in the death-stack. Overall the design is nice: fairly speedy and a good ceiling height, armed with two cannons and a grapeshot cannon. Limited it to TL1 components in case I wanted to use it in a campaign as an early vessel. And as such, moderately cheap.
First attempt at battle-testing it, the opposing ship simply ramps mine, destroying the grapeshot and one of the normal cannons. Second attempt, this time against a rather silly design of mine armed with nearly a dozen ballistae, it proceeds to focus all the ballistae on the suspendium chamber(which shouldn't be possible, hit locations are more-or-less random), which detonates it.
