The band was supposed to accompany Megadeth on a run of dates in Mexico in late August and early September, followed by a U.S. tour in September and October featuring Amon AmarthSuicidal Tendencies, and Metal Church.

“We were really looking forward to these shows, but unfortunately, [Megadeth frontman Dave] Mustaine has chosen to remove us from the lineup,” the band wrote. “The reasons for our absence are directly related to a contract negotiation insisted upon by Mustaine Management – a negotiation that has gone awry.”

Mustaine has had a very busy day on Twitter, getting into a back and forth debate with a writer for MetalSucks.net and gradually sharing more details of a narrative in which he claims Havok was not paying its bills and behaving unprofessionally.

Tickets to the shows went on sale in July and some fans have already expressed disappointment that they will no longer be able to see the thrashers on tour. Fans in Mexico will be particularly disappointed, as Havok has canceled what would have been its first visit since 2013.

Both Havok and Megadeth are still scheduled to appear at  at the  in San Bernardino, Calif., Sept. 24.
