There still appears to be a problem with some river maps not working with some OOBs, as far as I can tell it happens when a large OOB is used, perhaps because the river stops the deployment.
We had four people all unable to lauch on solo with a map that has been used many times in the past, I manged to get it working in solo sometimes, other times not.....it has a bend in the river
Could the combination of a large OOB and the river bends be messing this map up ?.
