When age one hit, I spent a few hours and built a new room, in my cave base specifically for all the age one stuff, and I spent an hour making fishermans net and then a big vine farm so I could farm Mossy Cobblestone for aesthetic use sprinkled thru out said room. But for whatever reason, Mossy Cobblestone simply turns to cobblestone when placed stage one.

Unless Mossy Cobblestone has some special game breaking properties when used later, I really think this should be changed, for aesthetics, and building purposes.

Similar to ores, Mossy Cobble is hidden from you in the world until age 2. As you can craft it from age 0, this appears to be a mistake.

So you're saying mossy should be visable from age 0, or uncraftable until age 2?

I don't see an issue with making it visible sooner for aesthetic purposes.

On a similar note, the bit chisel is craftable in age one as soon as you get tin, but crafting it immedietly causes you to drop it.

Found the cause of that too, the "iron" chisel is in two stages (one and two) - it should only be in one as we've changed it to be made from tin.

Awesome, Glad I could help!

Indeed, thank you for the reports :)
