• manually inputted char data is not stored (but displayed)
• ppt import seems to not grab the chars from the match/group table at all

further points to investigate:

• does it happen with other opponent types too? (seems likely)
• does the same issue exist on smash or brawlhalle

fwiw i will not touch those smash-like wikis they are too fucked up (and that says a lot with me being used to all the starcraft2 weird stuff) ...

Seems to happen with SoloOpponents too: https://liquipedia.net/fighters/Special:LiquipediaDB/Esports_World_Cup/2024/T8

missing storage in the manual input case will get solved via #5402

i don't see a reasonable way to enable char import those wikis (fighters and smash) are just to fucked up ...
if one adds the chars to opponent data on match level the entire display breaks:
