Escort Tag woes

[Lastmango]

I'm trying, very unsuccessfully, to use the escort tag. Every time it hits it just locks the game and bot up. The character is standing directly besides the NPC being followed, but after that both the bot and game go unresponsive. Am I missing something in how it is used? it's a follow mission:

<Interact QuestId="4945" QuestName="Thorn in Our Side" QuestObjective="0" CreatureId="18888" CreatureName="Exile Field Agent" MapId="51" X="4909.52148" Y="-897.528442" Z="-2342.98242" RunOnce="true" />
<Wait Time="5" />
<Escort QuestId="4945" QuestObjective="1" Type="Follow" CreatureId="52088" FollowDistance="5" MapId="51" EndX="4824.793" EndY="-852.521" EndZ="-2620.70044"  />

<Interact QuestId="4945" QuestObjective="0" CreatureId="18888" CreatureName="Exile Field Agent" MapId="51" X="4909.52148" Y="-897.528442" Z="-2342.98242"/>
<Escort QuestId="4945" QuestObjective="1" CreatureId="52088" Type="Follow" FollowDistance="5" CompletionRange="10" MapId="51" EndX="4827.91357" EndY="-853.312439" EndZ="-2625.97046"/>

From my profile, only noticeable difference is 'CompletionRange="10", give 'er a go!?

it has to be wrapped in a while tag or it freezes the game.

Both these statements use the <Escort> tag found in your profile, which was very similar to mine minus the "Completion Range", which didn't have any effect on the final outcome.

Does not work:

<QuestIf Quest="4945">
		<Interact QuestId="4945" QuestName="Thorn in Our Side" QuestObjective="0" CreatureId="18888" CreatureName="Exile Field Agent" MapId="51" X="4909.52148" Y="-897.528442" Z="-2342.98242" RunOnce="true" />
		<Wait Time="2" />
		<Escort QuestId="4945" QuestObjective="1" CreatureId="52088" Type="Follow" FollowDistance="5" CompletionRange="1" MapId="51" EndX="4836.15234" EndY="-855.715759" EndZ="-2627.73047" />
