There were some (partly game breaking) bugs, and honestly I don't know if they were fixed in the few weeks of "beta" we had,
as I could not be convinced to do things like grinding 5k fate, again, just to have it wiped, again, 2 weeks later.
I can not remember seeing the bugs I am going to describe further down this post to be mentioned in the patch notes,
and as I said, I could not get any info on if they are fixed or not.
If you are a dev, please consider having a centralized, publicly visible list of (fixed) bugs.
If you are a player, and a dedicated and much advanced player on top, a vigilant one maybe even, and you happen to have witnessed one of these bugs being fixed or still being there, then by the love of the God Emperor, please respond here, thank you!
Crusader turrets do not despawn.
(I just saw that Psykers moving flame pillar spell did not despawn, so I fear it's all the same still)
Crusader turrets can not be cast if you have 3 already, no matter what.
Should be destroying/despawning the oldest turret if you have 3 and cast another, as handled in any other game.
(1) and (2) together have the effect, that you can usually only use 3-5 turrets on any given mission before they are unusable,
I guess I do not need to explain the implications.
The Perk "Self Flagellation" is bugged for the Psyker, GENERATING warp heat instead of removing it each second!
Being one of the more powerful and hard to get perks, and essential I dare say, this was incredibly annoying.
Skill trees are partly still not class specific, like, in the "Support" skill tree, when playing as Psyker, there are several "Focus" related skills (Crusader) that are not only useless for a Psyker, but also would be easy to fix and give the game a more unpolished look
Controls are bugged if using modifiers, like CTRL, the modifiers are ignored.
Simple example: I remapped moving to WASD and would like to have those and nearby buttons have 2nd functions with CTRL or any other modifier, but the modifiers are ignored.
I am glad to see that with 1.0 the performance improved, and this early Psyker perk (for casting 12 spells quickly) was not bugged out anymore, giving me a surprisingly good feeling about this release, at least until the server crashed...
