Re-release of Steve Gaudreau's "Rock Temple" Add-On
This Add-On was accidentally created as a paid Add-On, but it was meant to be free, so I'm re-releasing it. This explains why it wasn't loading for anyone (because no one had registered it to access its contents).
Please download the file linked below, unzip the archive, then move the file it contains to MapForge's "Add-Ons" folder. Go ahead and overwrite the original version of that file, if you had installed it.
SG's Rock Temple Add-On for Windows & Mac (42.8 MB)
If this Add-On doesn't load the very next time you launch MapForge, don't worry, it should load fine in subsequent launches (the first time it has to retrieve and update the Add-On permissions from the MapForge server).
For the record, MapForge Add-Ons are platform-independent. They contain only artwork and data, no code whatsoever.
