Hi,
if I rememeber correct it was once possible to add someone to his own squad while having an ongoing attack if the planets maximum numbers of players would allow it.
Now I can still send the invites but if the player accepts my attacks stop totally and so I will loose my attack.
Imho it is probably a bug fix in some way. At least I do not know why this was changed and I couldn't find a thread about it.
But it would be really cool if the attack would just get dropped. Imho that should be possible and I can't think of a bug that would be still effective if the attack would be dropped instead of being lost.
Then the squad could at least take up the attack again without having to pay again.
The system right now is really annoying because one has to drop the attack. get somebody else to take it up for 20 seconds. invite the other person in that 20 seconds and have him accept and then the other one has to drop it once more and then it can be taken up by the squad...
I hope this is an workable solution that is not too hard to implement.
Have a nice day
