How your data is stored

Practicemode stores several things in files. If switching to a new server, you should copy these files along so you don't lose all your saved data. Data is updated on map changes, or when a user disconnects.

Grenade positions

Grenade positions are all stored in keyvalues files in the addons/sourcemod/data/practicemode/grenades directory as of 1.1.0.

Previously, there were saved in addons/sourcemod/data/practicemode_grenades.

Spawn names

Spawn names are stored in a keyvalues file in addons/sourcemod/data/practicemode/spawns.

Backing things up

If you value the grenades you have saved, I strongly recommend backing up the addons/sourcemod/data/practicemode directory. A bug in the plugin could potentially cause you to lose all grenades on a map.
