The issue link in the Modrinth page for the mod is incorrect. It should be https://github.com/AquUpd/GrizzlyBearMob/issues (same as in the Curseforge page), but it currently points to https://www.curseforge.com/minecraft/mc-mods/grizzly-bear/settings/issues, which is a privileged-access link, causing regular users to get redirected to the Curseforge / Twitch sign in page.

True, thanks!
