It seems to be the case that when you invite a friend to an event which they can’t attend that your relationship with them receives a little boost. This does make sense, as I suppose they feel that it’s nice to be invited. However, this boost still occurs when you invite somebody to an activity which they recently took part in. This means that you can, for example, invite all your friends out bowling. From then on, every day, you can invite them all again. They will all say no, but your relationship will be boosted with each of them. If you do this every day you can have a great relationship with everyone whilst rarely socialising with them. This feels like an exploit to me.
Also, just a minor bug; Going to church says it reduces loneliness, but it seems to increase it. I would think reducing it is the correct result.
Cheers for the game Cliffski, enjoying it!
