Is the build cost for level 4 an error? At Builder Hall 4 the maximum elixir that can be stored in storage units is 400,000 (250k in the Elixir Storage + 150k in Builder Hall). Even if you could take resources directly from your collectors to upgrade buildings, which you can't, it would only add up to a maximum of 421,600, still not adding up to 450,000. Is this a Supercell error or Wiki error? Or am I wrong?
