1. Create a simple mod
2. Put the following code in data-updates.lua
3. Launch the game. It crashes

for _, prototype in pairs(data.raw["corpse"] or {}) do
    prototype.animation = nil
    prototype.decay_animation = nil
end

This does not necessarily require animation and decay_animation, some other combinations also cause a crash

Thanks for the report. The issue was leaving animation_overlay and direction_shuffle defined for the corpses. I've added a check for the next release so it will error at startup instead of crashing if they're not also cleared.
