+X to Skills Not Actually Adding, Intended?

I'm not sure if this is intended or not, but I got to a point yesterday where a +2 to cold skills mod on my gear was not actually adding levels to my skills any more. I was at lvl 51, my skill gems were at 12, and my skill was adjusted to 13 with a total of +3 levels (with passive buff). This effectively makes the +2 on my gear have no effect and renders that otherwise nice mod useless. A shame.

Just thought I'd point it out in the case that the devs actually look in this forum.

I just tried a wand with +2 cold spells on it and it works, mind you that it only work on spells, not attacks, buffs, etc

Yeah, mine is also a wand (+2 cold skills) and it also worked up until the point where my level capped the skill gems. Meaning, it required my character level (51 at the time) to be higher to get access to the higher level skill gem naturally (all of my cold based gems). I leveled to 52 and now I have +2 to all of my cold skills, which is still not right, because I have the +1 to all cold skills (Endless Blizzard). So, yeah, I think there is something wonky going on here. Doesn't make sense to require character level = X to reap the benefits of a "+ to skills" mod. It kind of ruins the point.

So, I just moved things around in my inventory, a little testing, and now it's working. Very strange. Hopefully the devs are aware of this, definitely a bug.
