Other quest bugs :
'No element on the bottom lane' : completed after failing. I think it was meant to use Evil Roots, but it automatically completed after I lost a game.
'Having a hero equipped with Armor, Helmet and Shield' : completed just after checking it in the new quests, while my only character was a Knight with Armor, Ice Rod and Shield (no Helmet).
'4 consecutive hits with Boomerang' : I did 4 hits in a row with the same character, but dropped the Boomerang after the 4th hit. Quest was not completed. On another try, hit 4 times and recovered the Boomerang : quest completed.
'Kill Archeos' : does not complete either (tried twice) !!
- 'Having a hero equipped with Torch, Map and Compass' : completed when I freed the Knight with the Assassin !
- 'Having at least 6 Meat on the screen' has a Key icon.
The tally counting for "Kill X [monster type]" quests sometimes resets for no reason.
Also, Scroungers never steal Meat (I'm not complaining about that one :)
