Can buy helmets without expending iron ore

[Shaggy]

From examining the scripts, the file server-data/trunk/npc/woodland-village/ironore.txt does not check the levels of iron ore just before the transaction is complete, leading to the potential that players may dispose of the iron ore before that event.

Thanks for pointing that out, it's fixed in r4244.
Please could you post such errors on Mantis rather than the forums in the future.
