QuestCraft is maintained by a small team of volunteer developers. When users bypass official channels, it often complicates the support ecosystem. Official updates, such as the 5.0 and 6.0 versions which significantly boosted performance from 45 to 120 FPS, may not be compatible with cracked versions, leading to crashes and bugs that developers cannot fix.

If you're interested in trying QuestCraft, I recommend checking out the official Minecraft Forum or CurseForge pages, where you can find safe and legitimate downloads for the mod.
