Currently if charter stone is really far away and you don't have enough will to teleport, you aren't able to use it.
Change:
Allow to teleport from a Thingwall to a charter stone, even if you don't have enough will.
Travel weariness will be overextended by the missing value, so to teleport again a player will need to sleep/use other methods to lower travel weariness.
Why?
For early world trade / markets when a lot of spruces don't have enough will to teleport to charter stone (market)
