"Early in April"
I am. Doing the tree in German. Lots of us are. Including quite a lot of German speakers. I'm not jumping in your argument, just making a point :-)
These kinds of inconsistencies are starting to really get me frustrated. I understand throwing some new things at you, that make you have to go look up other resources occasionally, and mistakes CAN help you learn. However there have been so many of these lately, and there is nothing under the hints, or anything that would suggest what or why something is the way it is. It makes me really appreciate the people who do take the time to answer...the mods and the native speakers, but I wish there was a bit more to this.
