Multiple instances of Saving issues have occurred:

-----
1st Instance (173's Chamber: Intro)

*When Agent Ulgrin leads you to your final destination, you can save at the monitor. But, after saving at that monitor once, you can save forever without the need of any other monitor. (Stops after using the menu)

---
2nd Instance (173's Chamber: Breach)

*When Saving at the monitor, you can sometimes get a MAV. Most commonly occurred for me at the Map Seed, "S3rVive".

---
3rd Instance (Any Red-Timed lockroom + anywhere that has a monitor)

*When saving at a monitor, you can spam the save button 30 times after you save at a monitor.

---
4th Instance (Possibly a bug, Lockroom monitors)

*When saving, you can have a permanent Vigilante effect, like you do when staring at 895's images. They even happen when not looking at the monitors, it just drags you in.

---
5th Instance (Another possible Bug)

*You can save at any not lit up monitor. (I mean, without the light. Like in 1025's testing room, but 1123's testing room's monitor is lit up.)
