Disable "fail fusing"

Anyone know how to disable fusing of pets before the max level? I know it seems silly, but I have my reasons
many thanks

make the server unable to accept fusing (pet yard command packet id 3, make a handler for it) unless it wouldn't be a 'fail fuse', so the two pet levels acquired with the packet meet the level required. and if you really care about quality you could even grey the fuse button out (if the conditions are met, i'm not 100% but i think there already is a packet sending the client the pet levels) if you use an unobfuscated client.

Here is the handler. Sorry, but I don't know how to make the server unable to accept fusing if its a fail fuse. This is my first time with c# >.<
