I believe this started with my last session, where I got stuck in fishing mode on Deimos, unable to move or use gear. Was fishing, and while aiming with the spear got knocked down by several maggots attacking. My warframe took strangely long to get back up, and afterwards I was unable to move or use gear. Teleporting still worked, but no moving afterwards either, I ended up getting out by plugging in an xbox controller and bringing up the gear wheel that way to mount my K-Drive which seemed to have fixed it. Upon dismounting at extraction, my frame was still in the fishing pose when aiming, but not holding a spear anymore.
When I started up the game again today and headed to Deimos to fish, any fish that I hit with the (infested) spear just... died. I got the usual fish being hit sound and animation, but the fish just disappeared instead of the "fish caught" info screen/overlay popping up. The fish also didnt show up in the mission progress screen. This happened with every fish I found on Deimos, and with any spear I tested. They all just died as if being shot, but didnt trigger any of Sons voicelines about killing wildlife.
I tried (and failed) to record a video of this, and when I tried to record again I was unable to due to, well, not a single fish spawning in Deimos anymore. Ive exited Deimos and went back in, but still cannot find a single fish. Restarted the game, still no fish. Verified download cache, still no fish. Teammates joining my session on Deimos have fish spawn in like normal. I can find and catch fish in the other open worlds just like normal as well, just not on Deimos (which is really, really inconvenient when working on reviving all Deimos pets..........) .
