There is some wonky behavior happening with this code:

<GameModifier>
            <ModType>TacticalUnit</ModType>
            <Attribute>ChanceToLoseNextTurn</Attribute>
            <DisplayName>Slipped</DisplayName>
            <ApplyToTile>1</ApplyToTile>
            <DurationOnTile>1<DurationOnTile>
            <Duration>1</Duration>
            <UpdateDurationAtTurnStart>1</UpdateDurationAtTurnStart>
            <Value>.50</Value>
        </GameModifier>

What I'm trying to do is apply a an 'ice' effect to a tile which would have a 50% chance to cause a 'slip' effect (shown here) when moving into a new tile.  I have tried many hundreds of combinations of the above code to get this to work, but nothing is WAI.

Devs or fellow modders, can you shed any insight as to how these tags function together to work properly, and how I can use them to achieve the effect I described above?
