Hardwood production chains stop delivering when hardwood storage is full

Last night my storage for Hardwood was maxed out. While this was full the game would no longer allow Hardwood Planks or longbows to be delivered to my storage house's. The buildings were still producing just fine and as i had a full storehouse of hardwood, supply was not an issue. However at the end of production time nothing would get delivered.

Has anyone else noticed this, it appears that the game is seeing all the different forms of hardwood as 1 where the storehouse is concerned. If one of them fills up then it seems to think that all the Hardwood items are full and wont allow any more to be added.

Note - As soon as i created some storage space for Hardwood the Planks and longbows started to get delivered.
