C++ Detect opcodes errors

[tuxico]

I opened a TFS server 1.3, 10.98; And I'm using an OTClient 10.90 for portability and editing issues for an ATS.
When I do, I get the following error and some bugs in my skill view occurs:

ERROR: ProtocolGame parse message exception (474 bytes unread, last opcode is 2, prev opcode is 160): unhandled opcode 2

Apparently it's a bug related to the new skills, I believe, this was the only perceived change between 10.90 ~ 10.98 ...
How can I troubleshoot and detect these errors with only this message?
