Its not a mission I've made - it was inlcluded as part of the ECL_TAAB.zip file from the addons depot. I'm just unsure as to whether I have the mission.sqs'es which the screenshot is from are in the right place?
Maybe theyre looking for stuff in the wrong places? I have moved all the .pbo files from the .zip into the addons folder as instructed in the readme.
The actual addons themselves seem to work so far as I can tell...
Just these missions (which apparently show example bases using the addons) which are causing the problems.
