My bad. I assumed lodash.merge works in an immutable way. But instead it alters the orginal object. I will need to find a replacement for this line: https://github.com/ivanhofer/typesafe-i18n/blob/main/packages/utils/src/extendDictionary.mts#L24

It seems merge({}, obj1, obj2) is the solution.

Should be fixed in version 5.24.2. Thanks for reporting this issue.
