Thx for post, I pushed a small fix for this.
Didn't change version number for this, Should be live soon.
Inded the small pouch never breaks, but a small pouch can kepe you 2 extra runes each trip.
It would even take more time filling the pouch and unoting again,
Would also be a lot of work implementing it right there, so if you really really want it I could do it ... but it will not be worth.
