osTicket: 1.12
mariadb: 10.1.38
php: 7.0.33
apache: 2.4.25
os: debian 9 stable

Over the weekend upgraded from mariadb-server and client 10.1.38 to 10.1.40, which after that I got many emails of DB errors, including #1932, #1146, #2006. I rolled back the server and client versions to before the update, but database still throwing errors like

[DELETE `ost_lock`.* FROM `ost_lock` WHERE `ost_lock`.`expire` < NOW()]

Table 'osticket.ost_lock' doesn't exist in engine

---- Backtrace ----
#0 (root)/include/mysqli.php(199): osTicket->logDBError('DB Error #1932', '[DELETE ost_lo...')

From error 1932. When accessing the tickets, I get this logged to /var/log/apache2/error.log

The web interface is all functioning fine, ticket creation through emails and web interface okay, but there is nothing in the ticket menu and I am getting constant #1932 errors, which I couldn't find much about. Tried removing table but didn't do much, don't know much about SQL. Any ideas? Thanks
