There are a few cases where you'd really want quite substantial lengths of material when crafting items. Currently this affects mods only, but once those kinds of crafting recipes make it into the game itself they may cause issues.
The cases I've encountered or envisioned so far are:
- Making a net is going to use a whole lot of material, and I doubt 255 ft is sufficient (I haven't tried to convert the old recipe yet).
- Weaving (from thread) is going to require a lot of thread. The modified mod I've used bypasses the issue by still using a weight for the raw material, rather than length.
- Knitting. Similar to weaving, the length of the yarn is going to be rather substantial. The mod modification I've tried is to use two sets of wool, each 135 ft long (and I think 15 ft for ½ pound of wool is probably too short) to get the 270 ft required for the largest wool garments.
As indicated, it's not urgent, but something that may become an issue in the future.
