Updated mantle recently. Version 1.11.54 causes Tinkers to crash on startup. Made an individual instance for purely testing results in the same startup crash. Just using both Mantle and Tinkers Construct.

Hey no biggie. It's understandable I just thought to fill you in. Thanks for the heads up and sorry to disturb.

Also that usually happens with addons. Especially when significant changes happen. Authors kinda have to fix those eventually.

Yeah, Modrinth won't let me delay a new release because Modrinth is dumb. Just use the older Mantle for now.

Surprised that a return type change caused it to break to be honest.

it breaks the tinkers addons to

How are you expecting addons to work if Tinkers' Construct base doesn't work?

Released 1.11.55 on Modrinth which fixes this. Though again, that release is not supposed to be public yet; Modrinth just doesn't have delayed publishing options.
