Pofeve1 in the green circle, I've tested many times and is not saving items on that SQM.
You are correct. This specific tile does not belong to the house - I did not notice it before. I will have it fixed with the next map update. Thank you.
I hope you didn't lose any valuable items.
PofeveThe blue one circled SQM failed to save items once (on the first week I bought the house).
That is not possible to happen. This tile belongs to the house and it is being saved along with rest tiles within the house (as a batch). You must've get confused with the green tile or another player took the items.
Regarding other bug reports - thank you, I did fix them all. However, the map update is scheduled to happen along with the game content update, so it might take a while before the fix will be within game.
