Problems with Gatestone

[calmon]

I've a mysterious problem with the gate stone.

In one of my MP games (playing MA Ermor) i've absolutly no problem using the gatestone. I used it several time and beam whole armies through the map.

In another MP game (playing LA marignon) the gatestone don't work. I try to use it twice with different commanders and armies and after hosting the commander (+army) still stand in the starting province and has the 'defend' command.

I have no idea why it work perfect in one and do nothing in the other MP game.

In SP Tests it works well and never had a problem.

Any ideas what's going wrong? Maybe different client/server systems?
