Confused??? Paper Chase

To start my paper chase I've got to "Place 100 wood at the disposal from my storage" which is done, also "Raise my stock of wood every 100 pieces" which doesn't make any sense to me?? the amount changes if I open and close the Quest book, example, I just opened it, and it says 9/100 closed it, then opened it again, and says 3/100.

Any ideas??

You have to increase your storage total by 100 pine logs.So if you had 1000 logs in storage when you started the quest you will need 1100 to hit the target.So stop things that use your pine logs. coking plant,bow maker and sawmills and then buff your wood cutters to increase you stock.

Thanks, that makes sense :)
