Bug or Glitch idk

[Horizonseeker]

All Pokemon fainted but still was able to continue instead of being transported to pokecenter. I dont remember how it happened. One way i think that happened is a team rocket trainer previous to this bug used self destruct and for some reason my Pokemon fainted but i was able to still continue. The way i fix this error was letting one of the team rocket trainers i couldnt face see me where i was transported out of the building and i went and healed pokemon at pokecenter. This was in johto 3rd badge of silver server. While posting this it didnt provide me with prefix of silver setver so i picked gold to just post this bug issue.
