Error loading L10N assets

When building our game, we get hundreds of LogCook errors saying it can’t find localized versions of each of our materials. e.g.

LogCook:Error: Error loading ../../../Game/Content/L10N/en-US/Packages/[cut]Materials/MT_Wall.uasset

For 99.9% of assets we won’t have a localized version of the material.

How can we avoid these errors from filling up the build log?

These errors are an unfortunate side effect of how localised packages were searched for in 4.11, and the issue has been resolved for 4.12.

Thanks for the clarification.
