I found solution to bugged save games, not perfect but it's working
All you need to do is edit file SceneManager.txt in save slotx folder
for e.g. if you wanna go back to town just change last number to 1 in 1st line in this file, "Scene Index,Int,1"
and then load again save
if you wanna go to other location you need to do a little trick
1st save your game in current location you are
next go to desired location and save game again, but in different slot save, e.g. slot3
then go to your save folder and copy file SceneManager.txt from slot3 to your normal slot folder and replace it
once you load your save again you'll be in desired location with all progress saved
sometimes game is bugged after load your inventory and you'll end up falling down outside of map area, just start to jumping right after game load and if you do it properly you will be able to play normaly, if you fail just load save and try again
if you wanna unlock all costumes just open file Costumes Manager.txt, find line started with "isSet0,Bool,True" and change all text from "false" to "true" until line "isSet40,Bool,False"
