A recent update to Game Maker Studio has left many developers confused and frustrated after an anti-piracy system went haywire.
Those who use a legally obtained version of Studio have had game resources, such as sprites, branded with an image of a skull and crossbones. The resources are permanently edited, rendered useless.
Mike Dailly urged people to not assume those experiencing the issue were using pirated copies. He also speculated that the new delta updater could be the cause of the problem.
Although staff have encouraged users to run virus scans on their computers to ensure the program was not tampered with, reports of the issue have become more widespread suggesting it is an official bug and not an anomaly.
People who have recently updated Studio should make immediate backup copies of their projects.
Update: This issue has since been fixed in a recent patch.
