There has been some questions raised whether time-saving glitches should be permitted for salvage mode.

The rule is if you can exploit a glitch to save time, it's permitted. It's not different from using the elevator in certain survivor maps before it arrives or clipping through the door in Mission 10. If it's the programmers fault, you can use it.

Tool-assisted glitches (Cheat engine) or other third-party programs are still not allowed.

Additionally, it doesn't make sense at this point to draw arbitrary distinctions between which glitches are allowed/disallowed in any% type categories. For example, the maintenance jack clip in the main campaign and the keycard clip in Safe Haven (), neither of which require a third party program to obtain.

If there is interest in a "glitchless" category for either the main campaign or any of the DLC, it can certainly be added.
