Then probably you should write bug report here - https://forum.pandawow.ru/forumdisplay.php?f=161 I might try to reproduce this on my alt, to see if nothing has changed in past years. Maybe something got broken with this quest line and riding skill.

I guess you won't be able to restore macros , since they are stored in server. Consider creating them again.

For chat bar, did you try to reset any interface settings?

You have to redo entire quest line on alts to be able to learn it.
