I noticed a bug on my PC version of the game, where I would cloak and toss the smart disc. I would remain cloaked until the disc returned. At which time I would see my armor but the my predator was still cloaked. I decided to test this in a private match and from the FT perspective I decloak but I am still cloaked.
I made a video showing the bug.
You can clearly see me cloak, throw the disc, see it return and me become visible. You see me flash when I decloak from my end and then flash again when I cloak.
