Database errors do occur in osTicket from time to time and are not necessarily related to osTicket Awesome.

One thing that jumps out at me though is this atypical prefix:

Table ‘hsde_osti832.ost_ticket__cdata’ doesn’t exist

Does 'hsde_osti832' mean anything to you?

Not to hijack this thead but i have the same DB Error #1146<br />
<br />
This happen each time i try manual select to Choose Priority.<br />
<br />

Theme Information<br />
osTicket v1.10.4 // osTicket-Awesome-1.10.4-v1.0<br />
<br />

Your Software Environment<br />
PHP 5.5.38-1~dotdeb+7.1 // MySQL 5.5.60 // Apache/2.2.22 (Debian) web server<br />
<br />
Log error is the same each time.

[SELECT * FROM ost_ticket__cdata WHERE ticket_id = '12636']

Table 'localhost.ost_ticket__cdata' doesn't exist<br /> <br />

Ah, yes. 

The ability to change the ticket priority from the ticket list is an osTicket Awesome-only mod that has been troublesome. It is being removed temporarily from the next release and will return better than ever in a future release... with a no db-error guarantee!
