"This is normal. It's just slightly higher chance for it to be dropped from grineer. But it can be dropped by anything in the game." That's not how the drop tables work anymore though. Since Drop Table 2.0, it's mob specific. The only reason we say it drops from Grineer is because it's difficult to pinpoint the specific unit that drops the mob (and it could be multiple units).

Anyway, are you absolustely sure it was off an Infested, and that there were no Grineer nearby, or any other units (Stalker, bosses, etc.)?
