When creating a new world during spawn, this error appears and the world is not created. It helps to disable the mod, create a world, and then enable the mod.

Error while running event fast-hand-craft::on_player_created (ID 32)
No character.
stack traceback:
[C]: in function 'newindex'
__fast-hand-craft/control.lua:21: in function 'apply_crafting_speed'
fast-hand-craft/control.lua:16: in function <fast-hand-craft/control.lua:14>

You can disable mod before new game and re-enable it after cutscene, or change mod event on line 12 on smtng like "on_player_crafted_item" and modifier will be applied after first craft
