SAVEGAMES CORRUPTED

When I activated grandeur it asked for target player but the faces never flipped over.

All fixed in e422cc0

Prevent damage now works, but grandeur still doesn't flip faces so can't target player.

Fixed in 0e72735

Grandeur can target now, but the effect is permanent. Which is rather nice, but...

Fixed in 8f1b0b4

Now in Manalink dev 778ccb5 version Oriss,Samite Guardian granduer ability still lasts for ever. fixed
Also prevent damage works only as a shield it would be better if it worked manalink way,too so it works like (regeneration shield does) which regenerates like a shield and manalink way.

Fixed duration is till eot in commit 0d80589.
Edit: Changed above and done by drool66 properly in commit 11dd8f427.
