Disconnecting Frequently while training at Squids

I always get a runtime error when I am training at Squids, sometimes the whole client stopped and I have to reopen the game again. It happens sometimes when I am training at other areas, particularly disconnecting when I use Iron Arrow and Arrow Eruption.
I checked the troubleshooting guide but couldn't find my solution..

Disconnected Error Message:
Runtime Error!
Program: C:\Nexon\Maplestory\sxe7ee.tmp
R6025
-pure virtual function call

I am using a Macbook Pro.

Here is a screenshot when I disconnect, and the client freezes.

Sounds like you are using puppet when you play, I suggest don't before the new source.

 

I crash sometimes too when I am using my arrow eruption to mob at wolf spiders. Usually at the bottom pit when I stand at a safe spot to use my skill. That was without puppet on... is it an issue with my computer?

 

Sounds like someone was using door in the map and caused you to crash at wolf spider.

 

That may be the case for wolf spiders, it seems I crash whenever someone else is in the map together with me. I'll try to avoid using too much puppet with mobbing skills and see how it goes..
Thanks for the reply!

 

If you crash just because someone is in the map with you that's not how it should work.

Do you get any error code when that happens?
The error code you provided is the one you get when you dc because of the bug with puppet and it doesn't happen with any other skill.

 

Nope, there is no error code when I crash.. I only crash when using arrow eruption and not strafe/ice arrow. However this crash does not occur everytime, just occasionally

 

Some skill issues are solved by simply reinstalling the game, not familiar with any problems like that for those skills.

 

Ok, will try it out! Thank you!
