Hello players,
The player in question was banned for editing/modifying a file that was detected by the system. The general rules are that modification is strictly forbidden but there are exceptions of course. The file in question, still needs to be looked at to see what it affects. If it is found to be something minimal such as a monster spell (Pcloud, icestorm, etc.), the ban will probably be readjusted/lifted.
Afterwards, if the ban is still permanent despite the findings, a dispute is possible. With a dispute, another GM will validate if a rule violation occured and further, a team vote will decide if the ban should stay or be altered.
