So, I've got this quest today and the reward for it dropped significantly for some reason, normally its towards the top of quests Silver wise.

From what I understand quests for Fire Breathing Dragons are down to the same level as well. I am assuming this is a bug, since pets with those abilities do require some breeding work to do (so 100 silver for that sort of specification is not reasonable in my eyes).

Same here, but for Puma with Gracefulness:

Famous Artist is looking for a Puma with Gracefulness Reward: 100

Main Engineer of Mechanicians Guild is looking for a Dragon with ability to breathe fire to help with manufacturing

Thanks for reporting.

The bug is fixed. The quest prices were corrected. The reward will be correct for the quests which are already accepted and in progress right now too.

Sorry for the inconvenience.
