I'll add to this, I get similar problems.
Version: 0.1.12.2
Windows 10, pretty decent computer.
Tried with simplify AI (and without).
1.As the game progresses, and (I suspect) the AI has more and more things to check, even trying to do a simple 1 min action like suggest X takes about 4 or 5+ seconds to finish.
2.Another problem (very possibly related) is when first selecting an option, the game will sort of freeze for roughly the same amount of time as the above, even if that option just leads to more options. Example: Chat -> works fine for a few seconds then freezes for roughly 5+ secs then works fine again -> suggest -> works fine to freeze to fine -> Some suggestion -> freeze -> is good or bad -> shows initial text bubble then freeze for 4-5. Going backwards in a convo also causes it to freeze.
1. Is probably just optimization, too much/too deep or too frequent checks for AI.
2. Because the freeze time is nearly identical I suspect you're calling whatever function to check AI actions by accident each time an option is selected.
I can get a vid if you need it.
