Not replicable Skill Possible Blind 22 SP bug/ Random client Crash/Freeze

Lately I have been having random Client Crashes or Freeze (it just stops reacting within the hour)
At any time, Ive tested a few things: Bossing, using skills, not using skills either.
What came to mind is that the last thing ive changed to it was Upgrading my Marksman Skill Blind from 19 > 22

So i went to Cash Shop and used an SP reset 4th job and deducted my Blind from 22 > 21
now my Marksman has been online for hours fine...?
This looks like something the Devs might have to look into..

Im kinda nervous to upgrade it soon as i lvl up and add blind again 21 > 25 if this possible bug might appear again.

Marksman: Nereif

 

Blind 22 > 21

 

@gm/devs is it safe to go beyond 22Blind?

 

Well I haven’t heard of a mm with max blind to dc, so it should be

 

I've checked the wz files and did some independent testing... can't see any reason why this would occur. Perhaps it is coincidence. If you are able to replicate it in the future, please let us know.

 

with my latest Lvl up ive maxed out blind (21-30) and dont seem to have any issues at all.
Id say: case closed

(Although i would like Blinds duration to increase 20seconds (180>200) so its more insync with booster and SI)
