WPE Editing

So, I recently found robocraft and seen it's modding potential, but have had some problems. I am an experianced coder in C# and C++ so you don't have to newbify the answers if it's more than a setting. But I have seen that other than some offset tweaking and stuff you can use WPE to edit packets. Well heres my problem

WPE will only go for maybe 30 seconds until it hits 100% of the buffer and even if caught within the buffer non of the packet names will come up. So I can't find things such as blockdestroyed etc. Is there a setting I have set wrong for it to do this? Because any tut or whatnot I've read/watched it's not that way. Any help is appreciated.

Go to the options and increase the buffer to 1000 and check only "Send" type packets. If it still gets filled up that fast it's most likely a coding error with the hacked client you're using (if any).
