Hey Craig, thank you for your splendid uniform packs, but the recent update broke a mission from me.
Since I deleted the last version of SP pack, I don't have the old classnames anymore, so I can't find out which old classname hinders the mission to be opened in the editor. If you could post the old SPpack.sqs from an old example mission that comes with your addon pack, I could compare those 2 and come up with a "Find and replace" pair to fix my mission.sqm.
looking now, i didn't change any class names in the v2.2 update but i think i did in the v2.1 to add those extra version of the SSh68 Helmet, i haven't got the old SPpack.sqs mission file as it is always the same one, i update it as i add new stuff etc, i cannot seem to remember which one i changed, could you post the error message if it has one if not private message me and i will help you get back on track, sorry for that
