In game three against Ad Finem, ALOHADANCE lost internet connection. After using all of their pause time and two minutes of Ad Finem's, the match was resumed as a 4v5, which Virtus.Pro quickly lost. There were no issues the next game, but, according to accusations, Vega Squadron mid player No(o)ne was playing under ALOHADANCE's account.

LD has claimed that BeyondTheSummit is investigating the issue, but nothing has been proven yet. Virtus.pro has not yet made a statement regarding the issue.

UPDATE: Virtus.pro have confirmed that they broke the rules and will be withdrawing from The Summit 5. Ad Finem will be taking their place.
