They are lasting only half of what they are supposed to.

True seeing is only lasting 3.5 turns, when I cast it at a lvl 7 cleric.

IMproved invis lasted only 4 turns Cast by a lvl 8 sorceror.

Don't know about other spells, but it's a serious problem.

This happened during CLowland quest.

Yes, on the clowns quest, my Shield spell, Improved invisibility, and Invisibility spells. They all lasted 4 turns instead of 8.

I was asked by the above posters to test this and my shield spell lasted the correct amount of time.

I tested the shield spell after abandoning the quest (Without relogging or resting) and it lasted 1/2 its duration.

I relogged to test it again, and it worked the right duration.

I think this is only happening during CLownland Quest.

This is actually happening elsewhere with #/turn based spells. Hando Steel cast bulls on me and it lasted 3 minutes, instead of 7.

....on the goblin fort quest.

So it's something else affecting it.

Near as I can tell It's a bug in the nwn engine itself.

I've found that sometimes when this happens, all the animations will speed up as well.

Relogging will fix this, and there is not really much that can be done about it.

If no youtice it happening, just relog before you cast any more spells.

Add druid to the mix: Stoneskin (7) does not last 7 minutes, not by a long shot.

I've noticed this but it's not 100% of the time. Sometimes people's spells just fail a lot sooner then they should. Sometimes after a scant few minutes.
