So after some months break I've decided to came back to Warframe and obviously came across some weird and infuriating bugs.
When getting invisible with Loki Prime equipped with the Stalker Syandana, sometimes the Syandana rolls itself upwards, looking like a scorpion ready to poke something.
The Parazon Mod Swift Mercy doesn't work for Hounds or Thralls and sometimes even normal enemies getting executed on normal speed, rendering the mod useless and undependable.
When doing Kahl Mission to sabotage the veil facility, the first password is invisible sometimes, the third on the box disappears after alarm is set and the fourth disappeares when you get the other 3.
