1) when printing stack trace add to mod name the mod version if there is one.
*I've seen a number of mods use modVersion=___ in the mod.info file but it seems it's not something the game uses
2) When crafting spears not to use attached knifes, or favourited knifes.
3) Very often right click doesn't populate the worldobjects with what you click on, most noticeable when trying to add barricades through a collapsed (hidden) wall. Which is probably why I can't get barricade and add sheet rope options in a number of situations. So it would be very useful to add the barricade and sheet rope options to some other menu, like carpentry menu. This is obviously not for version 41, but something to keep an eye for in next version.
