Yes, that is true, since the total amount is constantly changing I decided it would be the best to correct that number once version 1.0.0 is ready. But I bumb the total number up to the amount you found in your screenshot! thanks for providing it^^
That's interssting, I will take a look at that, thanks for noticing!
1. Yes there is, it's in the western plains near the flower shop. (Except there is a bug that prevented it from spawing then i need to look that up as well later.)
2. Nope it currently isn't, but I finished it this month, will be avaible in coming version.
3. It currently does nothing. I tried around with a weight script, where the player would need to push a boulder onto it but I never got it to work, so currently that switch does nothing.
4. It's planned to be used in the end/post game so it currently has no use. It most likely will have no function in the near future, sorry about that.
