So I will try to list some bugs I found while playing the 0.63 version, sorry if the description sounds ambiguous, I'm doing it after playing so I can't give full details.

1 - Monsters inside the walls
       It's usually those plants that don't move, sometimes they are stuck at the wall and it's not possible to kill them
2 - NPC trying to kill those monster stuck at the walls
       When you have someone following you, they seem to have a behavior to try to kill any monster on the map, and when there are monster stuck at the wall, naturally they try to kill them but fail in reaching them, this causes the game to have some very extreme lag and absurdity slowness, it was awful to move to the stairs, but that solved it.

3 -  Dungeon/map being replaced after being explored.
       Sometimes a dungeon/map that I already explored is "deleted" and a new one is created. I guess this happens because I exited the game, but I'm not sure.
4 - Explored dungeons and maps showing as unexplored
      Sometimes a dungeon/map show as unexplored (like all black around the area that you haven't walked through) despite I had already explored them. This is most likely related to the 3rd bug when the dungeon is replaced, rather than being an old dungeon that "got dark" again, however, I guess some dungeons, like the power-plant, don't change, so they only get "dark" again.
5 - Items stuck at the wall
      This happens when a dungeon/map are replaced, which causes the items that you left on the previous dungeon being stuck at the wall.

6- Cannibal quest dude 
     I'm not exactly sure how I spawned him, but I think if you eat a human flesh or kill a person at a city (and eat its flesh?) he will spawn with a quest asking you to collect 5 items for his fellow cannibal friends.
      6.1 - First off, the Cannibal quest dude don't have chat lines, if you try to talk with him, it will trigger exception at the development console
      6.2 - When you try to clear the quest and go to the world map, there is, just like most quests, a yellow triangle guiding you to the quest destination, however, it leads you to the bottom left part of the map which when you reach there, the "!" is outside of the map and you can't reach there

7 - Igloo like structure at taiga not spawn
      When walking through the map, I found an Igloo like structure at the taiga snowy biome, but getting on the map triggered an exception and the Igloo didn't spawn, what I got in its place was the last place I was, which was a forest that was totally out of place on the taiga biome

8 - Exceptions at cities with chests
     Sometimes when walking on a city(on the world map), I enter in a structure that seems to be a big mansion at the top and 4 houses, 2 at the left and 2 at the right in the middle-bottom of the map. All of them have chest inside them, and just entering this map trigger some kind of exception, which doesn't seem to affect the gameplay though.

9 - Exception in my new house
      I found a structure that seemed to be my new house, there, just like the 8th bug, just by entering in the map you trigger some exceptions which don't affect the gameplay.

10 - Demigod
         I found a purple enemy called Demigod, just by entering on the map which he was triggered a lot of exceptions, when I tried to fight him, more exceptions were triggered, but unlike the before exceptions, now I couldn't move , but I guess I could still attack him, which I did and got killed. After that, I respawned at the new house, but I still couldn't do anything, not move, use a skill, item, anything at all. I decided to save and exit the game, but I couldn't load the saved file because it got corrupted due to this bug
(this was also what made me write the suggestion "Way to prevent the save data being lost due to any bug")

I haven't touched the game ever since, If you want some kind of game file that I have, tell me it and where to find it, also,  thank you and good job, the game was still very enjoying despite it being full of bugs.
