Thanks for the feedback. I haven't worked on the code in a bit, but I'll make sure to get to these things when I do. From memory:
I'm not sure what "trunk river water" is?
We never used the flint and steel, but I should just take it out of the game
Use the "other glasses" for brewing and drinking. There's two kinds if I remember. I think it's glass in a "U" shape? The same is used to collect spider poison.
I think the pipe is like a bow, put the pipe on the bar and the cooked weed to the right(left?) and use the pipe. Although honestly it's not worth the effort :) That's why I made Tom accept the cooked weed in trade!
If the tree trunk river water source node is placed, digging it by any method, including in creative mode, will crash the game.
The flint and steel depends upon an item which is unknown, therefore it cannot be crafted.
There does not seem to be any way to fill drinking glasses or flasks with a fluid, water in particular since this is required for brewing.
The pipe can be crafted, the pipeweed can be cooked, but the pipe seems to have no method to fill it with pipeweed.
