A bit of bad luck but mostly it was a result of your poor approach and lack of experience with troll raids.

Typically when a troll raid begins they spawn far enough away that you have the time to exit your base and lure them away before they can do any serious damage and since troll raids only occur after you've killed the second boss you should already have the equipment and experience to efficiently take out trolls.

Your second mistake was how you approached getting back to your base and getting your loot back. It isn't the game's fault that you chose to try go back at nighttime where there are more enemies and debuffs on you instead of gearing up a bit and waiting for day time. For some reason you also tried to rebuild your base when you hadn't eliminated all the trolls from the raid which is just kinda silly.

I hate to break it to you but it's kind of your own fault things went so badly, yeah the game can be harsh at times but if you had tamed wolves then you should've also had the knowledge and experience to avoid getting into such a situation and handling it so poorly. Don't blame the game.
