Something which needs to be done in the future, even AFTER the map bugs are fixed, is to match a OOB size with a map size.
There is little point in allowing a 300 CEH size OOB to be used on a 6k map, for example, there is simply not room for all those troops on that map.
From my understanding of Hooks comments, at the moment over crowding the map with "things" like forests can cause problems with deployment - and crash the game....even after this is fixed....I hope by allowing more things to be placed on the map.....there is still the sheer number of troops fitting into small maps.
Common sense on the part of us, the users, should stop this, but if there were some hard and fast system that STOPPED an OOB that was too large for the map that would be a usefull solution.
