(I thought I had reported this, but after doing query searches for 5 min, I can't find it.)
Citoid should not assume something was published on the 1st of a month if DOI only gives "Month and Year". Example 10.1263/jbb.105.192 only results in "March 2008", but Citoid assumes it then was pubished on the 1st of March 2008 (2008-03-01). Citoid should not do that, but just add "March 2008" to the reference on Wiki.
