New here, be gentle. And sorry if this has been hashed out already. Loving the game, by the way, and I haven't even gotten farther than building a rammed earth hut.
So, according to what I read in the wiki if you cook and eat a reed's roots (rhizome), it is gone forever. So you have to make a choice about whether you want to eat it or replant it, and if you eat them you will deplete the local reed population, leaving you without reeds to make baskets, etc. This gives me anxiety- I never want to eat one!
I propose that when you dig up a reed's roots there should be a small chance that two are produced instead of one. "Small" meaning less than than 0.1, though I'm not sure what exact figure would be appropriate. But 0.01 seems too small, so somewhere in between?
Anyway, then you could eat one now and again with a clear conscience.
