Three-quarters of all voting machines in Washington County, Utah, broke down early Tuesday due to improperly coded memory cards, County Clerk Kim Hafen told VICE News. The machines are now back up and running, according to local media.

Election officials scrambled to issue paper ballots in some locations, which quickly ran out, according to reports online. Paper ballots were not offered in other locations, such as St. George and Hurricane, local newspaper The Spectrum reported.

Hafen said there were four sets of memory cards and that three of the four were coded improperly, disabling the voting machines. Elections officials are in the process of recoding the cards and delivering them to the 36 polling locations in the county. “We are working to get them up and running,” Haven said.

Lt. Gov. Spencer Cox confirmed the glitch in a tweet shortly before 9 a.m. local time. “Good news! Washington Co issue isolated. Cards are being reprogrammed & will be delivered to polling locations soon,” he wrote.

Washington County is a rural area in the southwest corner of Utah encompassing Zion National Park. The county’s population was 138,115 as of the 2010 Census.

Reporters at the scene noted that some voters were quick to suggest foul play.

Utah is a swing state for the first time in years because of a strong third-party Mormon candidate in the heavily Mormon state, Evan McMullin. The former CIA operative is expected to take about 28 percent of the vote, according to an analysis of recent polls conducted by FiveThirtyEight.
