Should Indi spells immediately expire, when . . .

Hello,

When simply entering lair revies or colonization reives (e.g. say walking through or riding a mount) and, yes, participating, any Indi spell on me expires immediately. I tried putting it on just seconds before entering the effect area and in all cases it expired.

Why is this?

Is it correct or is it a bug?

Do the wikis document this event?

Thanks for your helpful input! :))
