[1.2.5] Game breaker : Permanent Invisibility

[fereor]

(maybe a duplicate of bug http://forums.te4.org/viewtopic.php?f=42&t=41779)

While using invisibility or secret of the eternals (I had both active when this happened), and under a certain circontance that I dont remember, my character has gained a permanent invisibility.
When checking my stats in debug mode, it appears that I have an game.player.invisible = 1.xxxe-15.
Its very few, but as I have not 0 in invisible stat, no foe with 0 in invisibility detection can see me. (and I still hit normally).

I know I give very few information about this, but I noticed only the strange graphical behavior first, and later on I saw that no orc could see me (or dragons btw)

I have done a bit more testing.
The bug does not appear when using invisibility alone (I played a skeleton shadowblade with invisibility)
The bug does not appear either when using secret of the eternal alone.

So it seams to be a combination of both which causes the bug.
(still testing to understand better)
