[Moas triggering alerts on spy missions]

Most Sentinels only have "guns blazing" or "don't attack at all" mode (with no precept mod equipped).
Shade has a precept that supports stealth by only attacking if you get attacked.

Kubrow/Kavat attacks are silent just like Deconstructor (Helios exclusive Sentinel Weapon) but most weapons are not.

I don't think it's a bug. MOAs are rather big machines with lots of moving mechanical parts. They are probably rather loud just moving around and not built for stealth.

[Goopolla size error]

Last month small Goopolla were called large.
Seems like somebody "fixed" it by using find/replace all large Goopolla to small. 😁
