We received some reports that players were falling through a specific section of upstairs when their ethereal potion was running out. We made some minor adjustments to hopefully reduce the chance of this happening.
However, we are doing further testing and touchups to hopefully fully fix this issue.
On top of this, we are making further improvements and touchups to the game which will hopefully be coming in the near future.
Thank you for your interest and get exploring!
