Seamless co-op
- Russia route for Seamless co-op: with "Russia route" on (Online page or the Seamless co-op page), Seamless co-op now connects through the relay to the seamless server. Before, it went straight to the server, which networks in Russia block.
- Chalice glyph search finds every SuperMedo dungeon in Seamless co-op (server fix, live already).
