Constant client crash since last maintenance

I normally run 4-5 clients open at the same time. Used for vending,leveling, or just afking pets for auto feed. Ever since last maintenance my clients are crashing constantly. Roughly every 45min-1hr. This was never an issue for me before and nothing has changed on my computer. Anyone else running into this? No error message no nothing just instant client closed. Its affecting clients I'm actively playing on as well as ones that are just idle without moving. 

Hello there,

On which server do you play? I assume the crash happens without any visible error?

I'm on Chaos. No visual error, no client lag, nada just closes with no warning. 

I am also now having the same issue, it just started a few days ago.  I play on 2 computers normally, both were perfectly fine.  Now my laptop only will crash almost on queue every 2-10 minutes after launching the game.  Doesn't matter where in the game I am, dungeons, cities, etc... No crash log, no error, just force closes immediately.  I've tried all the fixes I could find on the forums here and being that this was not an issue at all until after the maintenance last week idk what else to do.

Just wanted to update people.  I fixed the issue myself, it was a stackhash error causing the constant crashing.  My solution was to enable DEP for the ragnarok application, this is by default disabled and normally shouldn't need to be enabled for anything besides windows services.  But for those who had the same issue as me and cant find a fix this might work.  Make sure to check your Event Viewer and find the crash report for ragexe.exe, if it says something like
