Hi Barako
That is sad to hear you lost all your files about your games, anyone making games can understand this.
Rpg maker gives a lot of issues too of its own,I really think they need to think more thoroughly their engine before releasing them.
Always making backup can save your games indeed, it will not protect you from unexpected issues but at least there will be not much to re making.
Rpg maker issues is one reason I slowed down on Yumi's Dream lately,
I sure would have given up if I had no backup.
I hope that your mental health will be better with time 💪💪
