Whale Bug List

[MiloAkerman]

Whales have long been buggy. The following should be fixed ASAP.

• Without methods to defend against parasites, they quickly get full of barnacles.
• Upon death, whales not always sink as intended and will occasionally explode on sea_surface.
• Vestigial legs now deprecated; update to fully aquatic form.
• SLEEP_ANGLE will eventually drift to 90
