I leave my bot on and go and do something and come back and it's closed, this didn't happen ever, i use masterfarmer clestial which is flawless, but now my bot just closes?

1) CPU Overload

 

2) You have multiple tabs open but only signed in on one account which means the other clients will close shortly (To prevent people multi tabbing without VIP/Sponsor)

 

3) I don't know #3 sorry.

Load up your client again, this time try to babysit it for a while.

You might see two things:

• A green error; something that you'll need to paste here.
• It'll just close. This means this is CPU related. 

delete osbot client and reinstall java and redownload the client, to save some time delete the client and redownload that and then check to see if it works or not, if not do the first thing that i said

same thing happeneds to me

i has the same issue  

even if i babysit it just close like i press X but i dont and it cant be a cpu overload as i have a Intelcore i7 3800k i can run 5 league of legend clients before i notice a fps dropp so that isnt the matter also my cpu has tempreture doesnt rise at all  it something else.
