Jedi Robe armor bug?

[Intrinsic Bibimbap]

I found Qel-Droma's Robe today. Normally, I wear Calo Nord's Armor as a Guardian because even with knight speed 3 and the armor buff at rank 2, it still offers higher armor than when I'd wear a Jedi Master Robe combined with the two buffs.

So since Qel-Droma's is armor 5, I thought maybe it'd finally be worth wearing a robe. Put it on and cast the buffs, but my armor only goes to 30. It's 36 with Calo Nord's on with the buffs active. So I tried on a regular Jedi Robe by accident with the buffs going, and it is still 30 armor. I said to myself, what? So I put on Qel-Droma's again and the armor stays at 30. That makes no sense. It has 4 armor on the robe more than a regular jedi robe, how is it only staying at 30.

Is there some kind of a hard cap of 30 armor when wearing Jedi Robes of any kind?

It's likely the overall AC just caps at 30. Since enemies have to roll a D20 to determine a hit or miss it's incredibly unlikely that they would ever have a modifier high enough (At least +10) to beat an AC of 30.

Well, as I mentioned, I can currently get it to 36 by casting the two buffs and then switching back to the Calo Nord armor out of combat. So nope. I just never remember this when I played it years ago.
