When a long-lived integration branch has to absorb a small hotfix that only rewords user-facing error messages (and drops parsing of a third-party tool's own messages), the textual conflicts are the easy part. The silent breakage is in tests that exist only on the integration side and assert the old error code or string: they don't conflict, so git auto-merges them, and they fail later or assert stale behaviour. After resolving conflicts, grep the integration-only test and check files for the old codes and strings and update their expectations in the merge commit. Then grep the rest of the tree for the same old wording in components the hotfix never touched (other engines or launchers), and list them for the hotfix owner instead of silently extending the hotfix's scope inside a merge. Also validate auto-merged localisation catalogs (e.g. .xcstrings): parse the JSON and check that every key the code uses still exists.
