Batch #4896 by Millenium: 2 byte-identical, 2 confirmed by peer review.

- fn_18947 CMapChainEffect::sub_B4AB90: logic confirmed by peer review
- fn_18948 CMapChainEffect::Close: byte-identical
- fn_18949 CMapChainEffect::Slot01: byte-identical
- fn_18950 CMapChainEffect::Slot07: logic confirmed by peer review

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