Mythiq.net hosts no files for it. The download button goes straight to the release file on edge.forgecdn.net, so you are downloading from the author's own host, not from a copy of ours.
The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

Requirements
Game version
1.6.15
SMAPI
This is a SMAPI mod, not a loose content file. SMAPI — the Stardew Modding API, from smapi.io — must be installed first, and the game started through it. Without it the folder sits in Mods and nothing loads.
GAME VERSION
Built against Stardew Valley 1.6.15. SMAPI mods usually survive minor game patches, but a mod built for 1.6 will not load on 1.5.
DEPENDENCIES
Many mods require a framework mod as well — Content Patcher above all, sometimes SpaceCore or Json Assets. SMAPI prints the exact missing name at launch; a red error naming a dependency is the usual reason a freshly installed mod does nothing.
Installation
1. Download the archive with the button on this page and unzip it.
2. Move the mod's folder into your Mods directory:
3. Start the game through SMAPI, not the normal launcher. SMAPI lists every mod it loaded at startup — check yours is there and did not print an error.
UPDATING
Delete the old folder before unzipping the new one. Two copies of a mod is the classic cause of duplicate items and crashes, and unzipping over the top keeps stale files the new version no longer expects.
This release downloads from edge.forgecdn.net, not from us, so
there is no checksum to compare against. Scan the archive before you unpack it.

someone else, or anything that looks unsafe. Reports go to our review team, not
to the author.
