Updating server from 7.6 to 7.7

[Korv]

I am currently trying to update Avesta 7.6 to support 7.7.

I have successfully gotten my character list to be shown in the client, but as soon as I login to the gameserver the client debugs, it's always the same error message:

Debug Assertion 7.7 Objects.cpp 267 Sun Sep 12 22:37:23 2010 Windows Version: 5.1 build 2600 on 2 with Service Pack 3

In(Type,ObjectProperties->low(),ObjectProperties->high())

Is anyone familiar with this error message? If so, could you perhaps point me in the right direction?

I don't think it's a encryption problem since I have successfully disconnected the client when trying to log in to the game world, and those packets have been encrypted with XTEA.

The problem occurs when "sendAddCreature" is sent to the client, I don't know where and I really don't feel like backtracking every byte sent, so I thought I'd ask here first.

So if you have any clue, please tell me.

Link to Avesta 7.6: [7.6] Avesta - v4 - The Best Old School (This is actually not the version I am using, it has been removed but this one is close enough.)

I am not trying to make the server accept both 7.6 and 7.7, I am simply trying to make it accept 7.7.

Sincerely yours,

Why dont you just use the 7.7 sources?

 

[Korv]

Would you mind linking me to one of the 7.7 sources? I haven't been able to find one.

Mods, you can close this thread, my problem as been resolved.

What was the problem? Because I'm getting the same problem when getting my server to be compatible with 8.60.

So, what did solve this issue?
