Assisting Pipspook causing crash

When Wendy try to assist a pipspook the game will crash.

And the problem seems to locate in line 68 of lost_toys.lua

[00:31:51]: [string "scripts/prefabs/lost_toys.lua"]:68: attempt to call field 'unpack' (a nil value)
LUA ERROR stack traceback:

I have done some research and I heard DST using lua 5.1, so it seems to use unpack() instead of table.unpack() ?

so changing line 68: inst.AnimState:SetMultColour(table.unpack(MIN_FADE_COLOUR)) may able to fix this problem?

I love this Wickerbottom refresh, thanks you guys
