# Objective Fixes #16104 ## Solution I removed all instances of `:?` and put them back one by one where it caused an error. I removed some bevy_utils helper functions that were only used in 2 places and don't add value. See: #11478 ## Testing CI should catch the mistakes ## Migration Guide `bevy::utils::{dbg,info,warn,error}` were removed. Use `bevy::utils::tracing::{debug,info,warn,error}` instead. --------- Co-authored-by: SpecificProtagonist <vincentjunge@posteo.net>
