Oh, i think i c now, so nana grabs when shes not supposed 2
Probable Causes:
1. Too fast for nana- Remember, nana may be controlled by you but she is still a CPU, try to let her keep up, not so fast...
2. Nana is recieving grab command instead of shielding- Once nana is desynch from popo in any way, she will do more uncontrolled things(Rolling to get back to popo, running back to him, jumping back, attacking including grabs, etc.
3. Nana does whatever she is commanded in a certain range only - Remember, Nana will not do what is told once she leaves 4-5 steps from popo, keep this in mind when fighting larger chars.
4. Is it Wi-fi?- If your playing over wifi, its going to be harder 2 grab chain than normal, due to lag, connection, and nana's reaction time. I dont try to play Ic's online anymore for this reason...
5. Ask yourself,"Is it too advanced, do i need practice, who can i do it on well?"- It may just be difficult to pull off sometimes, many are with me. but b creative, if you cant do it make your own! i did, i have many if u wanna hear them, just ask!
Is this what your looking 4?
If not, ill keep trying, we will get your situation under control.
