Medic Archive

Ok, I've gotten to the part where I can make Action packs/woundpacks, BUT I cannot use it. I know I can only use it on campsites, hospitals, droids... we had a camp set up so I can heal my groupmate's wounds, BUT (again) I still get that same message that I can only use it in hospitals, etc... Is this a bug? or do we need a bigger, bettercamp to be able to heal wounds? Iam still kindaconfused with howmedic's healing works. Sometimes it'll let, sometimes it won't. Confusing.

Thanks for all the help in advance!
