WARNING: If you see no local scripts when you load Script Factory v0.52, it is because your local scripts need to be moved to the Local Scripts folder! You may move them at:

"C:\User\OSBot\Data\ProjectPact\OSRS Script Factory"
Mac:
"User\OSBot\Data\ProjectPact\OSRS Script Factory"
Mirror mode is currently getting worked on now with some very nice updates! I’m sure MGI will be posting more information soon! Stay tuned, and please don’t spam any of the developers asking when it will be released. Just be patient and it will come soon enough!
