Subject: [PATCH] Decompile 2 functions in Source/Contents/NavigationSource.cpp

Batch #5110 by youko: 0 byte-identical, 2 confirmed by peer review.

- fn_19567 CNavigationManager::ReadTargetObject: logic confirmed by peer review
- fn_19578 CNavigationManager::GetMobInfo: logic confirmed by peer review

Peer-reviewed-by: Yommy, alisonrag, Bruwuno, tayoba
Accepted without human review: peers confirmed the logic ("same" ahead by at least 3, with 70% of the votes).
