Besides the normal export, the arsenal also features an export via ctrl-shift-c, which exports the custom loadout in a syntax suitable for "CfgRespawnInventory", which means, that it can be used in decription.ext, to define custom respawn classes WITHOUT the use of zeus.
this is essential for having the classes available when starting the mission.

The problem is, that this way of exporting does not export weapon attachments and uniforms. The "CfgRespawnInventory" expects weapon and attachments in one class (for example: "arifle_MX_ACO_pointer_snds_F"), while the arsenal would only exports the base weapon ("arifle_MX_F") and ignore the attachments.

For the uniforms, the arsenal exports "uniform" instead of "uniformclass". This can be easily corrected of course, by manually changing the line to "uniformclass"...
