Trying to get property of non-object při ref() – Nette/Database

Ahojte,
prosím, prosím pomocte zoufalci.
Používám Nette Database (snad korektním způsobem) a z nenadání mi začal vyskakovat error Trying to get property of non-object na všech stránkách kde se pomocí ref() odkazuju na jednu jedinou tabulku. Zkoumal jsem to a podle mého je problém v cachování, ale teda nemám páru co dělám blbě, jelikož stejné použití metody u jiných tabulek neni problém.
Ze začátku když jsem vymazal cache a šel jsem na čerstvou stránku, tak se jednou zobrazila, ale po druhém načtení zase přestala fungovat :(

Dávám příklad jedné stránky na které mi to vyhazuje. Problémová tabulka je c_state.

CREATE TABLE c_state
(
  id_state serial NOT NULL,
  name character varying NOT NULL,
  background_color character varying,
  CONSTRAINT c_state_pkey PRIMARY KEY (id_state)
)

CREATE TABLE t_reports
(
  id_report serial NOT NULL,
  uid integer NOT NULL,
  id_person integer NOT NULL,
  eid integer,
  id_state integer NOT NULL DEFAULT 0,
  date timestamp without time zone NOT NULL,
  content text,
  summary character varying NOT NULL,
  motivation character varying,
  cid integer NOT NULL,
  CONSTRAINT t_reports_pkey PRIMARY KEY (id_report),
  CONSTRAINT t_reports_cid_fkey FOREIGN KEY (cid)
      REFERENCES t_companies (cid) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION,
  CONSTRAINT t_reports_eid_fkey FOREIGN KEY (eid)
      REFERENCES t_events (eid) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION,
  CONSTRAINT t_reports_id_person_fkey FOREIGN KEY (id_person)
      REFERENCES t_contact_persons (id_person) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION,
  CONSTRAINT t_reports_id_state_fkey FOREIGN KEY (id_state)
      REFERENCES c_state (id_state) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION,
  CONSTRAINT t_reports_uid_fkey FOREIGN KEY (uid)
      REFERENCES t_users (uid) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION
)

CREATE TABLE t_companies
(
  sys_uid integer NOT NULL,
  sys_date timestamp without time zone NOT NULL DEFAULT now(),
  cid serial NOT NULL,
  name character varying NOT NULL,
  url character varying,
  description text,
  address character varying,
  active boolean NOT NULL DEFAULT true,
  oid integer NOT NULL,
  CONSTRAINT t_companies_pkey PRIMARY KEY (cid),
  CONSTRAINT t_companies_oid_fkey FOREIGN KEY (oid)
      REFERENCES t_orgs (oid) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION,
  CONSTRAINT t_companies_sys_uid_fkey FOREIGN KEY (sys_uid)
      REFERENCES t_users (uid) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION
)

Presenter

	public function renderShow($id) {
		// Vrací $db->table('t_companies')->get($id)
		$this->template->company = $this->repo->findById($id);
