When using cloak and smart disc, a visual glitch occurs which shows predator armor visible. Also I believe the stamina glitch is tied to the smart disc.
When using the smart disc the screen stutters making it hard to aim. Now I believe this is chalked up to latency.
Also if you use second wind then use the smart disc, the second wind icon will glow blue as if it’s ready to use when it’s not.
