No worries and no stress man ^^
its only cause im lazy (and blind, aparantly) it seems =P just found a way to change sprites and lock them to animations but its fiddly and not very intuitive xD
have you thought about making attack/harvest animations without weapons or tools in them? that way you could change what kind of tool or weapon you are using instead of changing the sprites, so you could have the same animation set for sword, axe, spear or hammer, pickaxe fishing rod and so on.
