Loremaster Ward Duration

[Zan]

The duration of -ward from the LM Secrect Knowledge of Warding appears slightly broken. Having cast it I would have expected it to be the same duration as that granted by ESF: Abjuration, which is hours / level this is based on prior experience with other characters, and supported by the wiki (http://wiki.nwnarelith.com/Console_command#-ward).

Having cast it recently for the first time it appears to last turns / level and ONLY based on LM levels not total caster level

Live Server Character:
10 Paladin / 10 PDK / 2 LM

Steps to reproduce:
Cast Ward
Observe that duration appears to be turns / level from LM only (2 mins)

Expected result:
-ward should last hours / level

Idealised result:
Hours / level by effective caster level (Whichever class got the requisite SF & GSF feats)
