I am fairly new here, and i don't have days of playing VS, but having some experience in developping and fixing computer issues, I can definitely tell that having 5 worlds suddenly crashing is not normal.
First, as a lot of people already told you, if they all suddenly crashed and got corrupted, that cannot be the game, or at least, it cannot be while using the game the right way. You where apparently using mods, and as another minecraft player, i have to ask you : did you checked if your mods where working, not only when you downloaded them, but also when updating them, to the point you pushed your computer to his limits ? I was doing so when i was playing minecraft, and i never lost a game due to mod incompatibility when i did so.
Then, how did you reacted when you lost your world ? Did you tryed to make new worlds without mods to see if it worked again ? Did you tried to play again with a different version of the mods ? When reading your message, i felt like you didn't even tried to make it work ...
I might thinking about it too quickely, but i feel like you just rage quit like a kid, without trying to fix things, without even trying to ask for help. I feel a bit like your message means just "good bye, and have this never-responding message to talk with", and this is very triggering for me. Even more since you just said :"this more stable block game". I hope your not talking about minecraft. I played this game for multiple years, I don't remember exactly how much, but this is around 10, and i almost never felt like this game was stable and well made (feeling that just grew with time) . Between the language it have been programmed with, the bugs that end up beeing called features instead of getting fixed, the lack of realism so high i don't understand how i have been able to afford it, and even the developpement team that feel more and more like they think of us as dupe and easy money, i cannot let you say that. Minecraft suck, and i've been dumb trying to hope they will change and begin making minecraft a good game for 10 long years.
If you want help, first, help yourself. If you don't try to find the reason why your saves got corrupted, you will never get them back. Give logs, told what you did before the crash, and after it too. If you don't know how to get them, and have no idea why things didn't worked out for you, don't say "Vintage Story is not worth the Time or Money" or "I will be deleting this game". Say "I got all of my worlds corrupted, i don't have/know how to get logs, and i don't know what kind of information you need". This is way better. You have the right not to know even the most basics stuff. You have right to have issues. And you definitely do not have the right to stop everything because you got something that didn't go your way.
And if you don't want to report issues 24/7, just don't do the thing that make them happen : don't download update who are still snapshots or pre-release, which have chances not to work, check your game version and mods version before playing, after every new mod download and game/mod update, and think, before or after rage quit, i don't care about that. But just think about why things didn't worked out.
And let me repeat, i have experience in computer science and i played minecraft during ten long years, with mods and without mods. I know a bit what i am talking about.
And anyway, this game is still early access. He is not finished yet. Did you seriously expect not to have a single bug, or a single crash ? That's exactly why this forum is here. Stop using it to say "this unfinished game is not finished, i quit playing", and start saying "this unfinished game could be improved by doing ... , and I got the bug that do ... that must be corrected".
Sorry if i look a bit aggressive, but this kind of comment angered me a bit.
EDIT : You can also check already existing discussions and reports before creating a new ont. It actually is even better.
