Most 1.16.4 mods should work on 1.16.5 with the mods.toml updated to show it supports it

Works fine using Lost Trinkets v0.1.18 (lollipop 3.2.4, mc 1.16.5 and forge 36.0.10) for me.
Maybe try the latest version? The past couple versions are bit broken (my fault).

Oh I see what you mean, so the file needs to be tagged that it does support 1.16.5 on CF, no changes to mods.toml needed.

@BlueAgent , its cause @owmii has not made this https://www.curseforge.com/minecraft/mc-mods/lost-trinkets/files/3184790 work with 1.16.5. They only have 1.16.4 support not 1.16.5, so it does not sync with 1.16.5

The file seems to be tagged with 1.16.5 now. Can you see if it's working for you?
