Yeah, i think so.That "fix" doesn't seem particularly legit. I was curious, and it seems the developer, Zonitron Productions (aka AntEater Games, Broadplay Games, Crimson Duck Studios, Cubecumber Games, Digital Airony, Digital Carrot Productions, Floop Productions, GooCubelets Games, Netfork Studios, Pixberry Studios, Silicon Echo Studios, Sword Bubble Games, Zonitron Studios) released a whole bunch of asset flip "games" on Steam until they were kicked off. (Screwed some Kickstarter backers for one of their never released games as well.) I see this " fix" mentioned for other games also. I guess they all re-use the same IDs or whatever for the achievements across games.
DoneFixes like that aren't allowed unfortunately. It's mentioned in our rules and will get you removed from leaderboards on most other Steam trackers as well.
Please use this guide to relock the achievements: https://achievementhunting.com/guides/relock
If you suspect you used similar fixes on other games, I'd relock those as well as it may get you flagged here again.
Once you have relocked them, I can add you back to the leaderboard.
