I know the official Bugs thread says that there is nothing wrong with the Avengers skill that Hermits use, but this seems to be false for me. The skill does no damage at all (the numbers show up, but in reality it does 0 damage) Also, I've been training at coolie zombies and the meso drop rate is not 4x. More like 1x to me.
There is also a point in that thread about the pop-up for untradeable items but for me it works perfect. Maybe they still didn't update that or something.
Avenger and a few other skills were broken with the change to consumables (stars bullets arrows) and are fixed for this next update today. Also meso drop rate is known, and should be adjusted soon hopefully. Thanks for the info about the untradeable item pop up, it must've just been for my GM character only that it wasn't giving me the pop up.
