I understand the AIs won't trade with me if I'm too close to winning, but when does that kick in? Does it adjust to the victory conditions of the game? I feel like when I have 8+ points I can no longer make trades, even if it's a 20-point game.
The AI won't trade if it feels it's competing with you for a spot, so that could even happen around 3-4 points. And I've seen the AI trade with someone on the verge of winning, even with the current behaviour.
Thank you very much for the feedback. We have been able to identify an issue on older iOS devices and we are working on an update. We are doing our best to provide it next week. Thank you very much for your patience.
@Zenobia-AMKD@Gevondc it would be great if you could reach out to our support team via support@catanuniverse.com regarding issues with your account. Usually, we can´t help you with that here in the public forum.
@CGL You should be able to play offline as long as you haven't logged out of your account before starting the app offline. It would be great if you could reach out to us via support@catanunviverse.com regarding this issue. We will do our best to find out what went wrong.
@iTomm Why pay? Well, for a true Catan Addict this is only a rethorical question. We will do anything to play Catan.
To answer your question: I have read several posts of players demanding a refund.
Haven´t heard of anyone who got it, though. Read the contract, and you will know why: Garantees are explicitly excluded
I would recommend: Before buying another extension, try it out for a while and read the reviews and complains listed here in the forum. I held out buying certain features until I made sure they functioned sufficiently.
And yes, it is maddenly slow, but there is progress! In the long run.
In the long, long, long run.
because once you have turned your first 
you may "recycle" 
the settlement icon.
