The Coke Oven is bugged in the most recent update, so that's it for the content currently. A new update is going to release on Dec 27th that will fix that as well as add a ton of new content.
If you can spare the $1, Wonder Boy in Monster World is actually available as a virtual console download on Steam. Perfect game to kill some time before the update comes out. Otherwise I'm sure skipping around a youtube walkthrough would also get the job done for free.
trying to harvest the red flower things and they don't get picked up. it just gives me null, then when harvesting the % stays on screen (frozen) along with rescource assets. You are un able to leave, and if you try it wont let you move and the inventory just has the darkened back ground and nothing else.
