I was checking my mods for updates, and it said that Embeddium++ isn't available on Modrinth, which is where I downloaded it from. I checked the main website, and sure enough it's no longer there. The CurseForge page is still there.

Is there a reason this is the case or is it a mistake?

licenses, drama, modrinth and loans... is the most short version of it.
modrinth take it down, will be back... eventually. no ETAs.

Emb++ will stop begin updated on modrinth after release 1.3.0
