I usually change my configuration, depending on the items I get during the week.
Therefore, it does not seem like a good idea for 1 week to keep the same items and the same modules. Not at all, it’s not a good idea.
You mean that there are players who send you fake invitations, just to see if you are in the chat or are playing at that moment. And they set up their mechs so that if they meet you in battle, they can defeat you.
You have some options to avoid this. First, go to the workshop, take any torso and don´t put legs, put it in the box with the number. 1, then refresh page. Put again the mech you will use in the battle. When the person wants to send you an invitation to play, whether you are in chat or not, the invitation will be rejected.
Option 2: Disable the option that any player can send invitations for friendly battles. It´s the most direct, but I didn´t place it as the first, because it isn´t working to me now.
Option 3: When someone fills your screen with yellow letters of invitation, take a break. Get to campaign for a while. Coins always come well.
Option 4: do the same! The player who is sending you invitations is because he wants to play pvp! So you go to the workshop, set your mech to beat him, and go! Then ask for battle. When the other meets his modified mech, he will be surprised!
