I often see that people cannot install some addons correctly !
Here and now... ***once more a "LAW"
Dear MODDERS and INSTALLERS !
The BIS addons folder is a FORBIDDEN PLACE".
There is no need to put any additional pbo into the original addons Folder !
As you can see there are a lot of @addons on the "market" ....
So please be so kind and use your mods like this ones and it will help a lot.
In these @addons folder you can put your filestructure like in the whole BIS Root folder
*** *** addons
*** *** ***map_misc.pbo
You can do a lot more of this things but i do not want you make you confused.
And please do not say i do that since years and have no probs because it maybe ... and others do install their Arma again and again from scratch because they do not know what they have done with overwriting needed files.
