Migrating issue from FTBTeam/FTB-Interactions#835

Closing since focusing on new version (full rewrite)

Looks like an issue with the search box trying to call a client-side method on the server.
I'd suggest trying to break and replace the manager since that sometimes fixes issues, but in this case I doubt it would help. Will try and get a fix once off work.
