I think I broke my save file. After beating 7th gym I got a call from Looker (game version 2011232_9 2020-11-24 Build) and quit the game for the day. Next day I noticed the game was updated, so I downloaded new version and resumed my game. I went to Goldenrod, but there was no Rocket invasion. I checked the radio tower, but nothing was out of ordinary, except I could talk to the radio show hosts on 2nd floor, who told me they are grateful for repealing Team Rocket. I explored the game a bit, then went though the Ice path, fought the rival and got another call form Looker. I flew to Goldenrod and this time it was full of Rockets, and there were police officers in front of the radio tower. I went inside, and saw "Silver" standing in front of staircase, but I couldn't interact with him. I watched HeroVoltsy's playthrough, and saw there was supposed to be Looker in front of the radio tower, but he wasn't there in my save. Also, I can't revive Areodactyl from Old Amber, despite reviving other fossils.
I attached my battery save and my VBA quick save.
