Small but important patch

Do you remember this changelog:

• Dungeon re-generation should take less iterations now ?

Well, seems my "improvement" caused serious problems with dungeon loading. Should be fixed now (and the improvement stays :) )

Unfortunately you will need to create a new world :( There are some more fixes in this version (0.1.8c):

• Removed async from some flows (cleanup, save / load)

• Cooking null reference exception fixed

• Loading game after first tutorial step (lighting torch) blocked next tutorial step

• Fixed dialogue with Artificer after he repairs the tablet

• Fixed Fortress exits bug

• Dungeon level size is now being saved

• Shelf in tutorial room is properly loaded now

• Objects positions are now saved using Vector3 instead of Vector3Int

• Fixed dungeon exit spawning rarely next to tutorial room bug

• While cooking known recipe but didn't save the game after discovering one, the game didn't recognize it
