We have released Nesting Material item in Monkey Business. It has 6 uses and costs 60 SB - enough for 1 full nest for a lioness in need.

I am reminding that you can create a nest for your huntress on last day/last minute, it matters only for birth. We just had to give nests to all pregnant lions on Lioden upon launch so you wouldn't suffer the cub death issue upon login, and your huntresses will suffer this delay only this one time. Lioness without nest complete won't show pregnancy stage and you can hunt her freely!

Layout issues
Layout megathread - you can see Clayton's post there with compiled reports and there's coder questions for every report. If yours is there, please check the question and answer if you're able to!

Trading info
Every time a lion is traded, it has a cooldown and cannot be placed in trades again until one more rollover happens. This is to stop people exploiting the system to create monster lions.
