Please, report all issues here. This way I'll be sure to notice them and include them in the next version.
Version 2 fixes a particularly lazy gith knight, who cleverly turns invisible during the battle and then stands around doing nothing, instead of attacking suicidally. If you fail to notice him, you fail to kill him, get the wardstone and complete the quest. But no longer.
(If you have v1, you don't need to reinstall. Just use True Sight once during the first gith fight).
