After some testing, i found a way to grind hardwood crash-free for two weeks in-game. I'll leave this for the OP to try; see if it works.
- (To be safe) Avoid the specific area in that forest which cause the crash upon entering the forest.
- After harvesting hardwood, make the exit either through the Woodlands or the mines. Do not go the way you came in first (:If enter through the Giant's Village path)
- DON'T dash while making the exit.
- Once out of the ginseng forest, all is clear to dash on.
*Note: the crash seemingly surround on after harvesting hardwood. I suggest gathering other necessaries first before harvesting the hardwood.
To me, the crash area is always specific (the screenshot), so the crash location may be different for you. Hopefully this method works for the time being. Good luck
