Due to a major duping exploit issue, Trion was forced to take Trove offline for a good part of yesterday. Trion apparently worked through the night to fix the issue, bringing the game back up in the wee hours of the morning.
The reason for the long downtime is that the exploit actually had enough of an effect on the economy that it took some time to fix it — partially due to Trion wanting to avoid a rollback. As part of the solution, Trion is banning the players that knowingly made use of the exploit. They also removed all the duped items. As they noted, “99.999% of players will only be affected by the downtime, and none of the other changes.
While the service is now up again — it came back up around 12:30 Pacific — a few of the game’s features have been turned off until they can get everything completely cleaned up. In the meantime, Trion will definitely be offering some form of compensation for players. According to the forum post that kept everyone updated throughout the whole thing, that will “definitely” be happening sometime today.
