Ranger – “Defense” [Campaign 5, Mission 3]

1.6, which means this can already be considered a diagnosis :( It's a shame to leave it unfinished.

The mod I linked to fixes these bugs in version 1.6. If that doesn't help, contact the mod author directly.

valleriv, I also didn't experience any glitches while playing the Tribes of the East campaigns in version 3.0, because there are no enemies scripted to capture a specific town. The glitches appear when playing the original campaigns.
