Missing Crossguard stance

@futhark16  Did Drya Thornne respawn too?  I ask because of this thread:

Let me know if the same thing happened in your game.

So not sure if this helps your issue but i had an issue where i unlocked the crossguard stance fought some enemies then iut of no where the stance and saber disappeared. I found a way to fix it but no guarantees. Just because this worked for me doesnt mean it will for you.

I went to the cargo landing deck, took the elevator down, picked up a echo i missed then zip lined across to the other meditation point. I spam fought the raider whos hiding around the corner after the droid for xp about 7 times... (spam fought as in killed him and rested then went back) lastly i used the meditation point to fast travel back to the superstructure and went to the work bench.

Boom eveything reset and i got the stance and saber back. Long story short you might just have to fast travel and fight enemies idk. Trying to help more than EA is.

This happened to me too, and what I did to fix it was to restart my PS5, and that did the trick. Crossguard stance came back, and the tree skill opened up. 

Jedi Survivor is a good game, but has many bugs. I also experience speech and substitle problem, where the NPCs talk in supersonic speed. Sometimes the voice also disappears in the middle of the game. At first I thought it was my TV or sound system, but it wasn't. But just like the missing Crossguard stance, a quick restart on PS5 fixes all of them pesky bugs.
