In the latest version of the game, if you go into the noer sewers and try to access the goblin cave, some reason the game thinks a day has passed. This occurs when entering or exiting the goblin cave via the same entrance.

I don't think this is suppose to happen.

I think that's implemented in the game and  im playing at the stable version 0.9.8.5 the day passes like normal through entering and exiting the goblin cave, its kinda make sense since the way is veeeeerrry very long and Lona needs to travel that shit her way through the mountain caves

yea, thats intended, Moving between maps passes time.
