Today is your lucky day! I'm fixing the issue with Sweltering Heat as I type this.
As for the other issue reported: [Retractable Blade's bleeding effect disappears after a tick of damage is resisted] - I am not able to reproduce that. Whenever I see a resist, it keeps on ticking (unless it was the last tick of damage). However, if the initial kinetic damage from the blade is resisted, then the bleeding effect will not be applied - that is working as designed.
I did not see it mentioned in today's patch notes so it doesn't surprise me that this is not fixed at this time. Can you confirm that this is still slated to be fixed in an upcoming patch?
