No, the addons are definately in the res/addons folder, perhaps the o.pbo file has not recognised the files as existing, as it maps the addons in your folders doesn't it? Our clan has carried-out a cleanslate policy, due to too many members having different addons.
Everyone had to delete all existing addons within the main addons and the res/addons folders, then from an ftp site, download all clan official addons to the res/addons folder, with only the original addons in the main addons folder. Are there known issues of addons not being created in the mission sqm file? All the addons appear to work, its just I constantly receive error messages. :-\
Thanks in advance.
