Warframe bug spawns giant spider

In Warframe the Giant Robotic spider that is spawning around inside of the hub is anything but good. This bug has been having the spider spawn in the hub which is supposed to be a safe place for the players to trade with different merchants. The spider is meant to stop players that are to chaotic and is certainly not supposed to go into the one safe-zone players feel comfortable in. Reddit User Organicview as even posted numerous selfies with this creature venturing into the safe zone and has posted them on Imagur. The question is this one of the plans that the developers had in mind when they created this game or is this a legitimate bug?
