If you use the Advanced Tactics mod, you will probably encounter the following issue:

You can't see some objects. It may be an invisible wall, or it may be some invisible object that is located in front of you.

The problem is that the game or the other mod doesn't provide a solution to this issue.

If you are looking for a solution to this issue, you should definitely check out this mod. It is an advanced mod that will solve this issue.

The way that this mod works is very easy, but you need the Advanced Tactics 3.0beta to use it.
